frustrated

Its frustrating when you have a friend you wnat be friends with but they think you can "just get over" your PTSD. Im so mad I want to shake her because she doesnt grasp that I am not using it to control everyone bc I ant to be cntrolling,,she doesnt undertans I have to live in a rather controlled enviroment in order to not have panic atacks and potentially kill mysel. She also thinks tha the suicide is my way or getting what I want. How do Italk to someone who will not open thier mind or change thier opinion.?
