Ello guys... haven't been posting much lately but still practicing and going out. I have come across a situation that is absolutely KILLING my game, and I really need some help/insight.

backstory: I am 18, senior in HS. I'm now taking accutane for my backne... my face is fine but it's really bad on my back. With accutane, you are not allowed to drink alcohol. I should say it's "recommended" not to but it's known that the chemical in accutane (isotretinoin) is hard on your liver so drinking really isn't a good idea.

Problem is... I'm a senior in HS; so that means all my social life is based around house parties and drinking games and such. Not being able to drink is an absolute KILLER. I'm the only sober person in the parties, not able to play drinking games, and i'm really having trouble having a good time. My dad always said "you know you have an alcohol problem if you can't have a good time without it". I don't think I have a problem, but I really can't bring myself to have too great of a time. If I'm with my close friends, then yeah i'll still have a sweet time cause I'm familiar with all of them. But tonight I went to a party in another town where I knew nobody and though I still made small talk with the girls there, i just wasn't on my game at all. It became a snowball effect and throughout the night I just started having a worse time. I try to tell myself that it will all be over in a few months and I can tough it out, but I CANNOT spend my weekends sober for the next 4-5 months. I've been drinking energy drinks before the parties just to get a little hyphy, but it's not working like I want it to.

My question to you guys is:

a. Is there any substance I don't know about that can give similar effects in social situations like booze can? (not pot, I'm not a fan of burning at parties)

b. General tips? I really am lost and getting down on myself, especially after tonight's useless attempts at flirting.
