What Is Complex Trauma?

What Is Complex Trauma?

When we think of trauma, we may picture a single overwhelming event, such as an accident, natural disaster, assault, or sudden loss. But trauma isn't always a single moment. For some people, traumatic experiences happen repeatedly or continue over months or years, particularly within relationships where safety, care, and trust should have been present.

These experiences are often described as complex trauma. They can affect not only how a person remembers the past, but also how they respond to stress, experience emotions, relate to themselves and others, and feel in their own body.

The effects can feel deeply rooted, but they do not have to define the rest of your life.

What Makes Trauma "Complex"?

Complex trauma commonly refers to repeated, prolonged, or interpersonal traumatic experiences. It is often associated with experiences beginning in childhood, such as abuse, neglect, exposure to violence, or disruptions in caregiving, although complex trauma can also occur in adulthood.

Research on complex trauma has helped us understand that repeated interpersonal trauma can have wide-ranging effects on emotional regulation, relationships, self-perception, dissociation, and a person's sense of safety.

Common Signs of Complex Trauma

The effects of complex trauma may not always be easy to recognize. Sometimes the ways you learned to cope became so familiar that they feel like part of who you are.

You may notice experiences such as:

• Feeling chronically anxious, watchful, or unsafe

• Becoming overwhelmed by emotions or having difficulty calming down

• Feeling emotionally numb, shut down, or disconnected

• Persistent shame, guilt, worthlessness, or self-criticism

• Difficulty trusting others or feeling emotionally close to people

• Difficulty setting or maintaining boundaries

• Avoiding people, situations, thoughts, or feelings that bring up painful memories

• Distressing memories, nightmares, or flashbacks

• Dissociation or feeling disconnected from yourself, your body, or your surroundings

How Therapy Can Help with Complex Trauma

Healing from complex trauma is not about erasing the past or changing who you are. Therapy can help you understand how you learned to survive difficult experiences, build a greater sense of safety in the present, and gradually develop new ways of relating to yourself, your emotions, your body, and other people.

At Inner Core Psychotherapy, we approach trauma with compassion and curiosity. Rather than viewing trauma responses as signs that something is wrong with you, we can begin to understand how many of these responses developed as ways of protecting you when circumstances felt overwhelming or unsafe.

This perspective is central to Janina Fisher's trauma-informed work, which reframes many troubling symptoms and behaviours as adaptations to traumatic experiences rather than evidence of personal defectiveness. Learn more about Trauma-Informed Stabilization Treatment (TIST) from trauma expert Janina Fisher.

Creating Safety in the Therapeutic Relationship

For people who have experienced relational trauma, trusting another person may not come easily. Therapy therefore begins with building a relationship in which you feel respected, heard, and able to move at a pace that feels manageable.

You do not necessarily have to begin by telling every detail of what happened to you.

Trauma treatment may include developing greater stability and emotional regulation before directly processing traumatic memories. Fisher's TIST model, for example, is phase-oriented and places significant emphasis on stabilization, safety, mindfulness, and understanding trauma-related responses before and alongside deeper trauma processing. Learn more about Understanding the Living Legacy of Trauma from trauma expert Janina Fisher.

Research and clinical work associated with Bessel van der Kolk have also contributed to greater recognition that traumatic stress can involve physiological and sensory responses, not only thoughts and memories. This is one reason many contemporary trauma approaches pay attention to both psychological experience and the body's responses to stress. Learn more from the experts at Trauma Research Foundation.

Therapy can provide a place to notice these responses with curiosity rather than judgment and gradually build a greater sense of safety, choice, and connection.

Tailored, Trauma-Informed Approaches

There is no single therapy that is right for every person who has experienced complex trauma. Treatment should reflect your experiences, symptoms, needs, readiness, preferences, and therapeutic goals.

At Inner Core Psychotherapy, approaches that may be incorporated into therapy include:

• Internal Family Systems (IFS): Helps you become curious about different parts of yourself, including parts that may carry painful emotions or have developed protective ways of responding.

• Trauma-Informed Stabilization Treatment (TIST): A trauma-informed parts approach developed by Janina Fisher that emphasizes stabilization, mindfulness, self-compassion, and understanding trauma-related responses as protective adaptations.

• Cognitive approaches: Can help you explore thoughts, beliefs, and patterns that may be contributing to distress and develop different ways of responding.

• Somatic Experiencing (SE): Brings gentle attention to sensations, emotions, and nervous-system responses, supporting greater awareness, regulation, and a sense of safety in the body.

Therapy is collaborative. The goal is not to fit you into a particular approach, but to understand what you need and work together in a way that feels safe, respectful, and meaningful to you.

Reclaiming Your Life

Healing from complex trauma does not mean forgetting what happened. Instead, therapy can help the past have less influence over how you experience the present.

Over time, therapy may help you:

• Feel more grounded and safer in your body

• Recognize triggers and respond to them with greater awareness

• Understand and regulate difficult emotions

• Develop greater compassion toward yourself

• Strengthen boundaries and relationships

• Feel more connected to yourself and other people

• Experience a greater sense of choice and agency

• Make more room for rest, connection, meaning, and enjoyment in your life

Healing is rarely a straight line. Sometimes change feels noticeable; other times, progress feels slower. Therapy can provide a steady place to understand what is happening and continue moving forward at a pace that respects you and your experiences.

You Don't Have to Carry It Alone

Living with the effects of complex trauma can be exhausting. You may have spent years trying to manage difficult emotions, stay in control, avoid triggers, care for other people, or get through the day without fully understanding why life sometimes feels so hard.

Those responses may have helped you survive experiences that once felt overwhelming. Therapy can help you understand them with more compassion while developing new ways to feel safe, connected, and present in your life.

At Inner Core Psychotherapy, we provide compassionate, trauma-informed psychotherapy in Ottawa and online across Ontario. We work with you to understand how past experiences may still affect you today and support you in reconnecting with yourself, your relationships, and what matters most.

You deserve more than simply getting through the day. A path toward greater safety, connection, and a life that feels more fully your own may be possible.
