I think a lot of us felt the way you do, and thought there was no way we could quit drinking without all these negative consequences - I won't have friends, I won't have a social life, I'll be awkward, etc. Understand, it's the addict voice doing all the talking, and it's all wrong.
But if quitting forever seems like too big a step, how about quitting for 30 or 90 days? Most people can stomach that idea, and if you give that a serious go you'll either (1) discover that you can't even manage that, and need more help perhaps from an outpatient program, or (2) discover that you can, in fact, live life without alcohol, and start to appreciate how dependent you were on alcohol once the fog lifts.
