C-PTSD
Complex PTSD develops after prolonged trauma, altering brain areas that manage emotions and threat response, leading to intense reactions and relationship challenges.

What actually is it?
Complex PTSD (C-PTSD) results from repeated or prolonged trauma where escape was difficult, such as abuse, captivity, or chronic neglect. Unlike single-event PTSD, it involves lasting changes in emotional regulation, self-perception, and relationships due to sustained stress hormone exposure affecting the amygdala (fear center) and prefrontal cortex (decision-making area) [4][7][9].
It's a difference in how the brain is wired, not a character flaw.

Real experiences
I spent decades thinking I was fundamentally broken. Learning about C-PTSD was the first time someone described my inner world accurately.
The hypervigilance isn't paranoia — it's a survival skill that saved my life. Now I'm learning when I can safely turn it down.
People say 'just let it go' but my body literally won't. Somatic therapy taught me my muscles were holding memories my mind couldn't process.
My inner critic sounds exactly like my father. Recognising that voice isn't mine was the beginning of everything changing.
I fawn so automatically I didn't even know I was doing it. Now I can catch it — not always stop it, but catch it.
Emotional flashbacks are the hardest to explain. Nothing 'happens' but suddenly I'm five years old and terrified. Naming it helps.

Frequently Asked Questions
Glossary of Terms
Emotional Flashbacks
Sudden, overwhelming emotional states that recreate feelings from past trauma without clear visual memories.
Window of Tolerance
The optimal arousal zone where a person can function effectively, between hyper- and hypo-arousal states.
Trauma Responses
The 4F survival reactions: Fight (anger/confrontation), Flight (avoidance/anxiety), Freeze (shutdown/numbness), and Fawn (people-pleasing/loss of boundaries).
Hypervigilance
Constant scanning for threats due to nervous system adaptations from chronic danger exposure.
Structural Dissociation
Fragmentation of personality parts into apparently normal (functioning) and emotional (trauma-holding) states.
Somatic Experiencing
Body-focused therapy that releases trapped trauma energy through physical awareness and sensation processing.
