You can get help in so many places! I personally attend an AA meeting once a week and found someone there that I get along with well and can help me stay sober.
Therapy doesn't hurt either.
The friends/social situation can be tough. I have friends I just don't hang out with all that much anymore. We drank together - that was really it. Take away the drinking and there wasn't much left to the friendship. I can't put myself in the situation where I hang out in that environment anymore, it will lead to bad things.
Best of luck to you - there are ways out but you have to take the steps to get there.
