I too suffer from post traumatic stress disorder. I dianosed myself because I had the majority of the symptoms; but I was never suicidal. I can not visit people in the hospital, work in the hospital, talk about it, avoid the issue, have bad dreams, and so forth. I will even change the subject if it comes up, or just clam up.
I wan't go to phycatrists any more; the last one; in high school, diagnosed me with agoraphobia and put me on medication that made me sleep all the time.
