Have you tried EMDR? If you find a therapist skilled in its use, its the gold standard. There are studies with functional MRIs that show changes in the brain after treatment. EMDR doesn't make you forget, it reduces the emotional pain associated with PTSD.
I have not. But I am at a point with my PTSD that I don't have issues doing anything anymore. I have bad days and good days but it also is mainly based off my anxiety. And I've drained any financial ability to actually see another Dr.
Too bad the early folks you saw didn't think of the best treatment instead of just good treatment. Take care of yourself. EMDR.com has a list of practitioners; some may work with you on payment. Good success! You
