I'm sorry you are struggling, it sounds very frustrating. You don't mention this but are you on any medications? Perhaps that could at least help you tone down some of the anxiety and ADHD symptoms. I'm not sure if meds would help the OCD at all. As for the PTSD, I would recommend a T that does EMDR. According to my T who is a trauma specialist, EMDR is the quickest way to improve the trauma issues. EMDR may also be able to help with the anxiety as well.

Good luck to you. I hope you can find someone who is willing to work with you where you are.
