Im so sorry this happened to you. Im currently working through some ptsd myself from childhood, but when I was 19 I lived with my aunt for a while who I did not know was schizophrenia and all of a sudden she used to stack furniture by the door and not let me out tii the morning, and I had to do my necessities in the bathroom floor on a newspaper. I had nowhere to live or eat, I kept coming back, until.i flew back to my moms dysfunctional house. I know how you feel.
