HI I am in need of advice on how to best help my 19 year old son who has severe ptsd from childhood trauma from an alcoholic dad and being locked in a room at a very young age. He has trouble knowing if he is still in that room or out of it. He functions well much of the time, but tells me he struggles almost every minute. He is very artistic and a good writer. These things help him focus and be calm, but often the subjects are very dark. He is out on his own now and having a hard time of it. I want to help him, but it is very stressful for me and my health.. We have seen therapists for years and have gotten some help, but we are both exhausted. Any advice?
