I second the notion that you would probably become highly depressive and melancholy. Granted, not everyone will react the same to a drug like alcohol, sure you might feel fine having one or two standard drinks occasionally but people who get drunk and use alcohol as a social lubricant, well that's because it impairs their thought process, removing inhibitions and making it easier to follow through on emotions... Would it really feel good to have limited metal capacity and overflowing emotion? Maybe it would dull the pain of your life for a little bit but I could see you (or myself) becoming reliant on alcohol very quickly.
If you do have a drink maybe try just something very light to start with, no Vodka.
That's a little bit of my insight into alcohol consumption, i'm 18 (legal age in Australia) and have still not had a drink whilst all my classmates are looking forward to getting smashed and passing out in a pool of vomit. Regardless of your mental issues I think you're a very bright girl and could find more nourishing ways to enjoy yourself :)
