A high number of C-PTSD sufferers are misdiagnosed, mismedicated, and spend time in psychiatric hospitals. I've been wrongly treated for psychosis, too. Anti-psychotics act as a depressant for me, so it was potentially lethal.
More recently I've been prescribed Pregabalin

For treating C-PTSD Bessel Van der Kolk, author of
The Body Keeps The Score, has listed
1 Symptom management
2 Creation of narrative
3 Recognition of repetitive patterns
4 Understanding the connection between internal states (rumination, dissociation, etc.) and self-destructive actions
5 Identifying key traumatic incidents; treatment with exposure therapy, EMDR and body work
6 Practising behaviours appropriate in interpersonal relationships
https://www.researchgate.net/publicatio ... mplex_PTSDIt's my belief that a feeling of connection with the therapist, providing at least one 'safe' person in the sufferer's life, makes the biggest difference. That being said, unless there's provision for indefinite therapy, it can turn out to be another disappointment.
As an older woman, I'm now writing my autobiography (creation of narrative). It's just for me at this stage, and I'm finding it therapeutic to revisit the worst as well as the best times in my life. It would be nice to have a miracle cure for the final chapter, but I suspect there isn't one. Two therapists have treated me with their variants of EMDR with no effect. You might have better luck.
Alongside that, I'm working on the idea of resilience,

Taking better care of yourself, exercising and eating well so you don't feel compelled to eat too much, may give you a platform for effective self-treatment. No one knows your quirks and hot buttons as well as you do, so I believe you have to trust yourself and find your own path through the maze.
