I need to quit drinking, I need advice.?

I have become so dependent on drinking alcohol it is disgusting, I have had a lot of fun, but I have also humiliated myself and hurt people around me because of my drinking. Honestly, it scares me to think that I wont drink again. I wonder how I am supposed to go to a party, or vacation not being able to have a drink. I am a fun person.. but having others around me drinking and being silly makes me feel like a bore. I don't want to expect others to stop drinking because I can not handle it. Especially my bf. How do I deal with this?
