I had to self-refer to the OSI clinic. I wasn't offered any support. Very much like my fellow witness, I was diagnosed with adjustment disorder as well. That I couldn't handle change was essentially what that was, but I had been suffering from PTSD for over 20 years. It was never identified or treated appropriately.
Finally, after I self-referred and the OSI clinic spent almost two months asking for a referral for me, I got in. It still took almost nine months before I got see somebody. It took another four months, or maybe five, before I actually got my first appointment with a therapist. There was an informal peer group that did help me a bit, but to be perfectly honest, it was what happened to me, and after I reported, it was much better for me to not say anything and to just keep my mouth shut.
I hope that answers the question.
