Complex Trauma and Complex PTSD Therapy
Complex Trauma and Complex PTSD Therapy in Hampshire & Online
Helping You Heal from the Lasting Effects of Childhood, Developmental and Relational Trauma.
Living with the effects of complex trauma or Complex Post-Traumatic Stress Disorder can feel as though your past continues to shape your present.
Even when the traumatic experiences are over, you may struggle with overwhelming emotions, persistent self-doubt, difficulties trusting others or a constant sense that you need to remain alert. You may expect rejection, put other people’s needs before your own or feel responsible for keeping everyone around you happy.
Perhaps relationships feel difficult, you are extremely hard on yourself or certain situations trigger emotions that seem much stronger than the immediate circumstances. You may also experience distressing memories, nightmares, avoidance or a persistent feeling that something bad is about to happen.
Many people affected by complex trauma spend years believing that there is something fundamentally wrong with them. In reality, these patterns are often understandable adaptations to experiences that felt frightening, overwhelming or inescapable. They are not signs that you are weak or broken.
I’m Dr Sonney Gullu-McPhee, a Chartered Clinical Psychologist who supports adults experiencing the lasting effects of childhood, developmental and relational trauma. Join me at my Petersfield, Hampshire clinic or online across the UK for tailored, formulation-led therapy to help you feel safer, understand yourself more deeply and develop healthier ways of relating to yourself and others.
Understanding Complex Trauma
Complex trauma is a broad term used to describe the psychological impact of prolonged, repeated or relationally based traumatic experiences.
These experiences may occur over months or years and often take place in circumstances where a person feels unable to escape, protect themselves or receive the support they need.
Complex trauma may be associated with childhood abuse or neglect, domestic abuse, coercive or controlling relationships, prolonged bullying, repeated interpersonal violence or growing up with frightening, highly unpredictable or severely emotionally unavailable caregivers.
When trauma occurs within important relationships, particularly during childhood or adolescence, it can affect more than individual memories. It may influence the way you understand yourself, regulate emotions, trust other people, manage boundaries and respond to stress.
Some people who experience complex trauma develop Complex PTSD. Others may experience anxiety, depression, dissociation, low self-esteem, perfectionism, people pleasing or recurring relationship difficulties without meeting the full diagnostic criteria for CPTSD.
Whatever terminology is used, the psychological impact of your experiences deserves to be understood carefully and compassionately.
What Is Complex PTSD?
Complex Post-Traumatic Stress Disorder, also known as Complex PTSD or CPTSD, is a recognised trauma-related diagnosis.
It can develop following traumatic experiences that are extremely threatening or horrific, particularly when the trauma is prolonged, repeated or difficult to escape. However, not everyone who experiences this kind of trauma develops Complex PTSD.
Complex PTSD includes the central symptoms of PTSD:
- Re-experiencing the trauma through distressing memories, nightmares, flashbacks or strong emotional reactions
- Avoiding thoughts, feelings, people or situations connected to what happened
- Continuing to feel under threat through hypervigilance, tension, irritability or difficulty relaxing
Alongside these symptoms, Complex PTSD also involves persistent difficulties with emotional regulation, a deeply negative sense of self and problems feeling close to or secure with other people.
You may experience emotions as overwhelming or unpredictable, or you may feel emotionally numb and disconnected. You may carry persistent shame, guilt or a belief that you are fundamentally damaged, unlovable or not good enough. Relationships may feel unsafe, and you may fear abandonment, expect rejection or protect yourself by avoiding closeness.
What Is the Difference Between Complex Trauma and Complex PTSD?
Complex trauma and Complex PTSD are closely related, but they are not the same.
Complex trauma describes prolonged, repeated or relational traumatic experiences and the wide-ranging psychological effects they may have. It is a broad descriptive term rather than a diagnosis.
Complex PTSD is a specific diagnostic pattern. It includes the core symptoms of PTSD alongside difficulties with emotions, self-worth and relationships.
It is therefore possible to experience significant effects of complex trauma without meeting all the diagnostic criteria for Complex PTSD.
For example, someone may struggle with shame, perfectionism, people pleasing, emotional disconnection, boundaries or recurring relationship patterns without experiencing the full PTSD symptom pattern.
You do not need to arrive in therapy knowing which term best describes your experience. Through careful assessment and psychological formulation, we can develop a shared understanding of what has happened, how it continues to affect you and which form of therapy may be most helpful.
How Complex Trauma Develops
Our earliest relationships play an important role in shaping how we understand ourselves, relate to other people, regulate emotions and experience safety.
Ideally, children grow up with caregivers who provide safety, love, protection, warmth, consistency and reassurance. Through these experiences, they gradually learn that they are worthy of care, that their needs matter and that other people can often be trusted.
Unfortunately, this is not everyone’s experience.
When a child grows up with abuse, neglect, fear, chronic criticism, rejection, emotional unavailability or unpredictable caregiving, their developing mind and nervous system must adapt.
A child who is repeatedly criticised may become highly self-critical in an effort to avoid making mistakes. A child whose emotions are ignored may learn not to express them. A child living with frightening or unpredictable caregivers may become constantly alert to changes in other people’s moods.
A child who experiences inconsistent or conditional affection may grow into an adult who fears abandonment, works hard to please others or believes that love must be earned. Someone who could not safely depend on others may learn to become extremely self-reliant and find it difficult to ask for help.
These responses often made sense at the time because they increased the person’s sense of physical or emotional safety. The difficulty is that they may continue into adult life, even when they are no longer needed.
Therapy can help you understand these patterns with curiosity and compassion rather than judgement, and gradually develop healthier ways of thinking, feeling and relating.
How Complex Trauma and Complex PTSD Can Affect Your Life
Complex trauma rarely affects only one area of life. Its effects may influence the relationship you have with yourself, the way you manage emotions, your relationships and your ability to feel safe.
Your Relationship with Yourself
You may believe that you are not good enough, that your needs do not matter or that there is something fundamentally wrong with you. These beliefs can contribute to shame, low self-esteem, perfectionism, excessive responsibility and a harsh inner critic.
You may find it difficult to accept praise, recognise your own needs or believe that you deserve care and support.
Your Emotions
You may experience emotions as intense, unpredictable or difficult to manage. Relatively small events may trigger powerful fear, anger, sadness or shame.
At other times, you may feel emotionally numb, disconnected or unable to identify what you feel. You may alternate between emotional overwhelm and shutting down completely.
These reactions may reflect a nervous system that has spent many years adapting to chronic stress and threat.
Your Relationships
If important early relationships involved criticism, fear, inconsistency, neglect or rejection, trusting other people may understandably feel difficult.
You may fear abandonment, become highly sensitive to rejection, struggle to say no or put other people’s needs before your own. You may remain in unhealthy relationships, feel responsible for other people’s emotions or avoid closeness because it feels unsafe.
These patterns are not signs of weakness. They are often understandable attempts to protect yourself from being hurt again.
Living in Survival Mode
Many people affected by complex trauma feel as though their nervous system never fully relaxes.
You may constantly scan for danger, overthink conversations, expect something to go wrong or struggle to switch off. You may feel guilty when resting or find it difficult to trust positive experiences.
Even when life is objectively safe, your mind and body may continue responding as though danger is just around the corner.
Understanding Your Patterns with Compassion
One of the most important parts of recovery is recognising that your patterns developed for understandable reasons.
People pleasing may once have reduced conflict. Perfectionism may have protected you from criticism. Emotional numbness may have helped you survive overwhelming experiences. Hypervigilance may have helped you anticipate danger.
Self-reliance may have developed because other people could not be trusted. Self-criticism may have felt safer than waiting for someone else to criticise you first.
These responses were not evidence that something was wrong with you. They were intelligent attempts to cope with difficult circumstances.
The challenge is that strategies which once helped you survive may now prevent you from living the life you want.
Therapy is not about judging or eliminating these parts of you. Instead, we work to understand why they developed, appreciate the role they once played and build healthier ways of meeting your emotional needs.
How Can Therapy Help?
Healing from complex trauma involves more than reducing individual symptoms.
The anxiety, shame, emotional overwhelm, people pleasing, perfectionism, avoidance, self-criticism and relationship difficulties you experience may all be connected. Rather than treating them as completely separate problems, therapy aims to understand the whole picture.
Together, we explore how your experiences have shaped your current patterns, identify what continues to maintain them and develop a personalised treatment plan.
Therapeutic Approaches That May Help
Because the effects of complex trauma differ from person to person, treatment needs to be individualised.
I begin by developing a comprehensive psychological formulation to understand your experiences, current difficulties, strengths and goals. This helps us decide which therapeutic approaches are most likely to support your recovery.
Depending on your needs, therapy may draw upon EMDR, trauma-focused Cognitive Behavioural Therapy, Schema Therapy, Compassion Focused Therapy and broader CBT strategies.
Eye Movement Desensitisation and Reprocessing
EMDR is an established psychological treatment for PTSD. It helps the brain process traumatic memories that continue to feel emotionally distressing or present.
For people affected by complex trauma, EMDR may be adapted and used as part of a wider treatment plan. Some people benefit from preparatory work before directly processing traumatic memories, while others may be ready to begin trauma-focused work sooner. This is decided collaboratively and reviewed throughout therapy.
Trauma-Focused Cognitive Behavioural Therapy
Trauma-focused CBT helps you understand and process the impact of traumatic experiences. It may involve exploring trauma-related memories, reducing avoidance and gently examining beliefs such as “I am not safe,” “It was my fault” or “I am permanently damaged.”
The aim is to help you develop a more balanced understanding of what happened and distinguish between danger in the past and safety in the present.
Schema Therapy
Schema Therapy is particularly helpful when trauma has contributed to long-standing beliefs and relationship patterns that began early in life.
You may believe that you are defective, that your needs do not matter, that people will eventually leave or that you must always remain strong and self-reliant. Schema Therapy helps us understand how these beliefs developed and gradually build healthier ways of meeting your emotional needs.
Compassion Focused Therapy
Many people affected by complex trauma live with a very harsh inner critic and carry deep shame or self-blame.
Compassion Focused Therapy helps you develop a kinder and more balanced relationship with yourself. It is not about ignoring what happened or simply thinking positively. It involves recognising that many of your current difficulties developed as understandable attempts to survive.
Cognitive Behavioural Therapy
Broader CBT strategies may also help with anxiety, worry, low mood, depression, avoidance and coping patterns that continue to maintain distress.
CBT can help you recognise unhelpful cycles, develop practical coping strategies and build confidence in responding differently to present-day situations.
Therapy Tailored to You
These therapeutic approaches do not need to be used in isolation.
Some people benefit from beginning with emotional regulation, grounding and strengthening self-compassion. Others may first need support with boundaries, relationship patterns or shame.
Some may be ready to begin trauma-focused work relatively early, while others need more time to develop trust, safety and emotional resources.
There is no single programme that everyone must follow.
Throughout therapy, we review your progress and adapt the approach so that treatment remains responsive to your needs.
What Working With Me Looks Like
Step 1
Free Initial Consultation
We begin with a free 15-minute consultation where we can discuss what has brought you to therapy, answer any questions and consider whether working together feels like the right fit.
Step 2
Assessment and Psychological Formulation
During the early sessions, we explore your life experiences, current difficulties, relationships, strengths and goals.
Together, we develop a psychological formulation that helps us understand how your experiences have shaped your current patterns and what may be maintaining them.
Step 3
Developing Safety and Emotional Resources
Before and throughout trauma-focused work, we consider what you need to feel sufficiently safe and supported.
This may include grounding, emotional regulation, understanding triggers, strengthening self-compassion and exploring boundaries. There is no pressure to discuss traumatic memories before you feel ready.
Step 4
Processing Trauma and Creating Change
When appropriate, we begin working more directly with the memories, beliefs and patterns that continue to affect your life.
Depending on your formulation, this may involve EMDR, trauma-focused CBT, Schema Therapy, Compassion Focused Therapy or a combination of approaches.
The aim is not simply to reduce symptoms, but to help you develop a stronger sense of identity, healthier relationships and a life that is guided by your values rather than your past.
Is It Complex PTSD or Something Else?
Many people living with the effects of trauma spend years trying to understand why they struggle.
Some have been told they have anxiety or depression. Others may have received diagnoses such as Borderline Personality Disorder, also known as Emotionally Unstable Personality Disorder, ADHD or another psychological condition.
Complex PTSD shares features with several other presentations. Difficulties with emotional regulation, relationships, concentration, low mood, anxiety and self-esteem can occur across a range of psychological conditions.
This is why it is important not to rely solely on symptom checklists or self-diagnosis.
A comprehensive psychological assessment considers your symptoms, developmental history, trauma experiences, relationships, coping strategies, strengths and patterns over time.
Whether your experiences are best understood as Complex PTSD, PTSD, the effects of complex trauma or another psychological difficulty, the aim remains the same: to understand you as a whole person and develop a treatment plan that reflects your individual needs.
Can You Recover from Complex Trauma or Complex PTSD?
Many people worry that they have been affected for too long or that their experiences have permanently changed them.
The encouraging news is that recovery is possible.
Recovery does not mean forgetting what happened or pretending that the past did not occur. It means developing a different relationship with those experiences so that they no longer dominate your daily life or define who you are.
Therapy may help your mind and body recognise that the danger is no longer happening, process traumatic memories and change the beliefs and patterns that continue to restrict your life.
Over time, many people begin to feel calmer, less controlled by fear or shame, more compassionate towards themselves and more able to build healthy relationships.
For people who experienced trauma in childhood, recovery may not mean returning to a previous version of themselves. There may never have been a time when life felt consistently safe.
Instead, recovery can involve discovering who you are beyond the adaptations that helped you survive.
It is about moving from surviving to living.

Do I Need a Complex PTSD Diagnosis to Begin Therapy?
No. You do not need a formal diagnosis to seek therapy. Many people experience significant effects of complex trauma without meeting all the criteria for Complex PTSD.
Can Complex PTSD Be Treated?
Yes. Although healing from prolonged trauma may take time, many people experience meaningful improvement through appropriate psychological therapy.
Will I Have to Talk About My Trauma Straight Away?
No. Therapy progresses at a pace that feels manageable. We begin by developing a shared understanding of your difficulties and considering what you need to feel safe and supported.
Can EMDR Help with Childhood Trauma?
EMDR can be helpful for many people experiencing the effects of childhood or relational trauma. It may form part of a broader treatment plan that also addresses emotional regulation, shame, boundaries and relationship patterns.
What Is the Difference Between Complex PTSD and BPD or EUPD?
The conditions can share certain features, particularly emotional and relationship difficulties, but they are distinct presentations. A careful psychological assessment considers your developmental history, trauma experiences and patterns over time.
How Long Does Therapy Take?
The length of therapy varies according to your individual experiences, difficulties and goals. Complex trauma often develops over many years, and meaningful recovery may take time. Your treatment plan and progress will be reviewed collaboratively.
Is Online Therapy Suitable?
Online therapy can be effective for many people. Suitability depends on your individual circumstances, privacy, safety and ability to engage comfortably in sessions. We can discuss this during your initial consultation.
