Glossary for CPTSD Healing

This glossary is a living document created for people healing from Complex PTSD (CPTSD). It will be updated over time as language, understanding, and community wisdom grow. Take what feels helpful, leave what doesn’t, and remember: needing clear and gentle explanations is a valid and important part of recovery.

Emotional Flashback

An emotional flashback is when you suddenly feel the intense emotions of past trauma in the present moment, even if nothing “obviously” dangerous is happening. You might feel overwhelmed, ashamed, panicked, small, or abandoned without fully knowing why. Unlike movie-style flashbacks, emotional flashbacks are more about feelings and body sensations than clear images or memories. If this happens to you, it doesn’t mean you are “too sensitive” – it means your nervous system learned to stay on high alert to keep you safe.

Inner Critic

The inner critic is that harsh, attacking voice inside that tells you you’re not good enough, you’re too much, or you’re always doing something wrong. For many people with CPTSD, this voice developed as a survival strategy – trying to keep you safe by criticizing you before others could. Over time, though, it can become cruel and exhausting, making healing feel harder. Learning to notice, question, and soften the inner critic is a big part of recovery.

Window of Tolerance

The window of tolerance is the range where your nervous system feels safe enough that you can think, feel, and function without being overwhelmed or shut down. When you’re within your window, you might still feel stressed or sad, but it feels manageable. When you’re pushed outside it, you might go into panic, rage, numbness, or dissociation. CPTSD can make this window feel very narrow, but healing work and nervous system support can gently widen it over time.

Freeze Response

The freeze response is when your body and mind shut down or go still in response to danger, real or remembered. You might feel stuck, paralyzed, numb, foggy, or unable to make decisions or move your body the way you want. This isn’t laziness or lack of willpower – it’s your nervous system trying to protect you when fight or flight doesn’t feel possible or safe. Many people with CPTSD know this as “shutting down” or “going blank” in stressful situations.

Fawn Response

The fawn response is a survival pattern where you try to stay safe by pleasing, appeasing, or caretaking others, especially people who feel threatening or unpredictable. You might ignore your own needs, say yes when you want to say no, or work hard to keep everyone else calm so you don’t get hurt. This response often develops in childhood environments where love, approval, or basic safety depended on keeping others happy. In healing, you begin to notice this pattern and slowly practice setting boundaries and honoring your own needs.

Fight/Flight Response

The fight/flight response is your body’s built-in alarm system that prepares you to either confront danger (fight) or escape it (flight). You might notice a racing heart, tight muscles, fast breathing, or sudden anger, panic, or restlessness. For people with CPTSD, this response can get activated by things that are not actually dangerous but remind the nervous system of past harm. Understanding this can help you respond with compassion to your reactions instead of blaming yourself.

Hypervigilance

Hypervigilance is a constant feeling of being “on guard,” as if something bad could happen at any moment. You might scan people’s faces and tone for danger, feel jumpy at sudden sounds, or struggle to relax even in safe situations. This state makes sense if you lived through environments where threats were real and unpredictable. Over time, though, staying this alert is exhausting, and part of CPTSD recovery is teaching your body that it is allowed to rest.

Dissociation

Dissociation is a way the mind and body protect you by disconnecting when things feel too overwhelming or unsafe. You might feel distant from your feelings, your body, your surroundings, or even your sense of self, like you’re watching life from far away or on autopilot. This can look like zoning out, losing time, or feeling unreal or “foggy.” While it can be frightening or confusing, dissociation began as a survival skill, and with support you can learn gentle ways to come back to yourself.

Triggers

Triggers are things that remind your nervous system of past trauma and set off intense emotional or body reactions, often before you consciously understand what’s happening. A trigger can be a sound, smell, tone of voice, expression, place, date, or even a feeling inside you. Being triggered doesn’t mean you’re overreacting or dramatic – it means your body is still trying to protect you based on old experiences. Learning your triggers can help you prepare, ask for support, and use grounding tools when they show up.

Grounding

Grounding is a set of practices that help bring you back into the present moment and into your body when you feel overwhelmed, triggered, or dissociated. This might include feeling your feet on the floor, naming things you can see, hear, and touch, holding something comforting, or slowing your breath. Grounding doesn’t erase the pain, but it can lower the intensity enough so you can feel a little safer and more in control. Over time, building a “toolbox” of grounding skills can make CPTSD symptoms feel more manageable.

Nervous System Regulation

Nervous system regulation means helping your body move out of survival states like fight, flight, freeze, or fawn and back toward a steadier, more balanced state. This can involve breathwork, movement, rest, supportive touch, connection with safe people, or other calming and energizing practices. When you have CPTSD, your nervous system has learned to expect danger, so regulation is not about “calming down on command” but gently teaching your body that safety is possible. It’s slow, patient work, and needing support with it is completely valid.

Complex PTSD vs PTSD

PTSD often develops after a single traumatic event or a few events, while Complex PTSD (CPTSD) usually comes from long-term, repeated, or childhood trauma, especially in relationships where you were supposed to be safe. Both involve symptoms like flashbacks, nightmares, and feeling on edge, but CPTSD often also includes deep shame, ongoing relationship struggles, emotional numbness or flooding, and a shaky sense of identity. If you have CPTSD, it’s not because you are weak – it’s because you endured too much, for too long, often without enough support. Naming CPTSD can be painful, but it can also be a relief to finally have language for what you’ve been carrying.

Trauma-Informed Care

Trauma-informed care is an approach to support and services that understands how common trauma is and how deeply it can affect a person’s body, emotions, behavior, and choices. Instead of asking “What’s wrong with you?” it asks, “What happened to you?” and “What do you need to feel safer now?” In trauma-informed spaces, providers work to offer choice, respect, collaboration, and emotional safety, and they try not to re-create power dynamics that were harmful in the past. If care you’ve received has not felt this way, that’s not your fault – you deserve support that honors your history and your humanity.

Inner Child Work

Inner child work is a healing practice where you gently connect with younger parts of yourself that were hurt, ignored, or overwhelmed. Instead of blaming those younger parts for how you cope now, you begin to listen to them, comfort them, and offer the safety and understanding they didn’t get at the time. This might involve imagery, journaling, talking to yourself kindly, or working with a therapist. For people with CPTSD, inner child work can be a powerful way to soften shame and build self-compassion.

Somatic Experiencing

Somatic Experiencing is a type of body-based trauma therapy that focuses on the nervous system and physical sensations rather than only talking about events. The idea is that trauma gets “stuck” in the body as incomplete survival responses, and by slowly paying attention to sensations, tension, and impulses, the body can gradually release some of this stored survival energy. Sessions usually move gently and at your pace, so your system isn’t overwhelmed. You don’t have to do Somatic Experiencing to heal from CPTSD, but many people find somatic (body-focused) approaches helpful alongside other forms of support.
