I am such an idiot. Never drinking again.

This might sound a bit over-dramatic. It is not. Seriously.
Went to a party on friday night and got more than a little bit wasted - so wasted it was that I couldn't lift my head up and at the end of the night I couldn't get up off the floor. In the time before this happened I made out with two different guys (I am such a slag!) someone (apparently) managed to get photographic evidence of this and me giving one of them a lap.... yeah. I also smoked weed and that made me feel amazingly happy. Yay.
I feel like such an idiot because I don't remember most of this (vodka + liquer + JD = wastaggggeee) and I think I'm going to go through a baptism of fire at school tomorrow.
Any ideas on how I can get through with my head held high?
