I'll apologize in advance for not having any words of wisdom or great advice. I don't know much about PTSD except that I have it along w/ some other stuff. Just know that you have every right to feel the way you do but don't lose faith on all humanity. There are so many good people out there. Try taking it down a knotch. I mean try not to analyze and just hear what people are saying. Give it a chance, just listen and not read into it so much. Maybe I'm naive cause I always want to believe there is more good then bad and if we don't try to give it a chance you can't brake the cycle. It's no way to live your life. I'm a pessamist myself so I just antcipate the worst and hope for the best. Sorta like rolling the dice but if you don't try you will rob yourself of any good that you clearly deserve.
I don't like giving advice but I hope some good will come out of it.
