I can totally relate to you man. I am 24 as well and recently realized I am an alcoholic. I have been sober 20 days or so and been going to meetings(often twice a day) for a week and a half. I know its not much yet but it is a start.
I realize that if I take that first drink I could do more irreparable damage to myself or others so I don't take that drink one day at a time.
It is hard, all my friends drink. I have dropped out of my social world and stay home, work, go to AA. I have not seen many of my friends since I hit bottom a few weeks ago. I just have to avoid people, places, and things that would encourage me to drink for a while.
