Whenever I go to a party where there's alcohol being consumed, I'm the one watching to see how much everyone has had and I get paranoid when I think somebody has had too much. I try to stay away from said person as much as possible, but I feel horrible about it, because these people are my best friends. I've been in the situation a few times where my friends have gotten sick and needed help, but I haven't been able to do anything more than hide in the farthest corner of the house and try not to hyperventilate. Even when my own boyfriend was getting sick all over his floor, I couldn't bring myself to help him or even go near him to say goodbye when I left. It isn't fair that my other friends are always stuck with janitor duty while I don't have to do anything. I've tried to explain my phobia to them, and they tell me they understand and not to worry about it, but I can't help worrying that they think I'm just being a priss and trying to get out of cleaning.
I'm going to college next year and this is going to be a huge problem.

Anyone have any advice?
