Nikko, I know I have PTSD. It is from a relationship in college that went horribly wrong. He treated me very badly after the relationship ended and told people that he wanted to hurt me. A very scary time.
So basically you feel all that sometimes at the same time!!! You basically are a walking zombie mess. Funny part is, that semester I was going through that hell, it was the best semester I ever had grade-wise. Go figure. Then again....looking back, it might have been the BP starting up and I didn't know it.
I wish you luck in finding out if PTSD is a diag for you.
