I know exactly how you feel, being around people affects me so much that i never finished high school or went to college, an I emotionally beat myself up all the time for this, but it is so hard to live with this problem. I hate to recomend pills cause that's just another dependency and with side effects, they say some pills aren't goood for your liver. Maybe you could wear a baseball cap, sometimes that helps me, sometimes wearing sunglasses helps me too so I won't have eye contact with anyone, but then if you are in class, well sunglasses won't help, I don't know, maybe you could do the 12 step program on here an see if that helps.
