my family was very destructive and unsupportive. I have ptsd from growing up with them. it was when I made the choice to cut them out of my life that I started to finally get better. it was as simple as making that decision and then no longer contacting them. no more calls no longer going to family functions not returning their calls. I didn't bother giving them explanations and they didn't bother asking. we just drifted apart. the ptsd symptoms went away after that. it was the best decision I ever made. take care.
