I was valedictorian of my class, but I am almost positive I bombed one or two of my four AP exams.....?

I had a nervous breakdown during my calculus exam and almost couldn't finish because I couldn't breathe (so I'm almost positive I got a 2 or 1 on that one)....I had a stats teacher who had never taught before, and he didn't know what was going on half the time, so I'm not feeling too confident about that AP test either...I studied for all 4 of my exams (REALLY REALLY studied) but now that scores will be out on friday, I'm panicking....Can someone ease my mind? Please help me relax when it comes to the possibility of failure :(
