This is just my personal opinion, so take that for what it is worth. My T and I spoke about this on several occasions. He mentioned that throughout his internship, his mentor did a study of women in high care houses for those who were considered mentally ill. A percentage of those residents, in the high 90 percentile, had be subjected to extreme trauma during their lives. His thought was that the PTSD comes first, the psychosis comes later. Deal with the PTSD and the psychosis may well right itself. Unfortunately, in the Canadian system (not sure about US), nobody puts the time into these women. They end up in these houses and it ends in a Hotel California kind of way. 'You can check out any time you like, but you can never leave'
Men, he said, were more prone to drug abuse and get lost in the drugs. I know you have had a past with drug abuse. Many people who are traumatized learned to you drugs in order to cope.
I think, if you go to this T and unwind this thing, that you will get to even ground again. First, deal with the dependencies. Then with the coping strategies to help you cope with unregulated feelings etc and then with the traumas.
