OCD/Trauma Combination?

Okay so I had somewhat of a traumatic experience awhile ago, i posted about that in a different thread, anyway more recently i get anxiety, kind of feels like residual anxiety, i feel like im shifting and evolving slowly which makes me excited because at times i feel like my personality coming back and it feels so awesome, anyway, at times i feel disconnected sometimes at school with friends or social situations, more recently, I have been having thoughts about images that i see of these teachers related to a somewhat traumatic experience, anyway i have thoughts saying that its thanks to these teachers that i became emotionally stronger and it feels strange knowing its thanks to them, the ones that did you wrong in the past are also the ones that forced you pretty much to become stronger, it causes anxiety, and i remember i blocked one of them on facebook, and now my thoughts tell me to unblock that teacher so i can "fully forgive them" but honestly how unblocking someone enable me to do that, they could be blocked or unblocked and that has nothing to do with the fact of forgiving them or not. I read books that say to just be with the feeling until it subsides, cuz honestly right now i feel like $#%^ and it feels really nasty in the pit of my stomach :/ sometimes i just hate breathing and wanna do drugs to get high and think of something else, but im not a big fan of drugs really, so i just really wanna know, do i just stay with these feelings and feel them until they subside and are released?
