Eagle, all the instant therapy in the world is not going to solve the problem that your faced with. That is the facts of the situation. Your mind has decided that your going to either deal with your trauma or it is going to continue making you worse and worse, without dealing with it. Even dealing with your trauma, get you hit the same low point... as you must go down to come up when PTSD is involved. You must be pushed to that worst point in life, so you can recover, be stronger, have no fear of trauma, then you still have to learn how to control PTSD itself.

I think your personally worrying yourself and creating more anxiety for yourself now, for something that no amout of instant counselling is going to fix for you in regard to your chemistry class and math. PTSD doesn't just go away because you get some immediate counselling... it just doesn't work like that.
