I'm living proof that you can get past it and live a happy, healthy life. Unlike nearly everyone else you might talk to, I don't see PTSD as an "illness". I see PTSD as just a label others put on you when they don't understand your natural reactions, which they classify as "symptoms". You don't have terminal brain cancer, your just reacting naturally to circumstances. You can verify this yourself by just looking around at all the others like you, and the existence of this forum and all the others like it. If your reactions weren't natural/normal, there wouldn't be all of these others who react in the same ways.
Like most who will post here, my "symptoms" were severe. It's a miracle nobody died before I was able to deal with my guilty, violent, suicidal, paranoid self. I would post a link to my online bio, except I don't think it's allowed it these forums.
Although my PTSD symptoms subsided, it wasn't from any sort of direct PTSD treatment. Instead, someone helped me learn to investigate how my (our) human mind works. I was as surprised to realize one day that my anger and resentment just wasn't there any longer. I can still be quite passionate when describing the incidents which lead up to my “symptoms”, but the feelings of being disillusioned, hopeless, helpless, extreme hatred, frustration, and anger which I would have felt when talking about them in the past, are no longer there.
I know how hard it can be to trust anyone, and that we all really just want(ed) is a pill or other remedy we can just take care of on our own. I didn't have enough trust to talk with a professional, or even others in the same boat as myself. I wouldn't have been able to bring myself to even ask questions in a forum like this one. But, if you can bring yourself to ask for more information, I would consider it an honor to point you in the right direction.
