Your not alone I have a few months stay in a shelter and my PTSD symptoms was more than it should have been. I just tried to cope with the good of it and my parts seemed happy and surrounded with love. The bad part yes was traumatizing. Keep up the good work in therapy try to process those memories. 1 year is a very long time then maybe you will be at peace. The subject might trigger you but not as much, therapy should help you cope with what was...try to rescript it when it ptsd is high regarding the subject..
