I agree you should make new friends, not try to salvage old ones that aren't helping you stay sober/be happy. You're leaving college soon anyway and most of those people (those who can't get it, likely) you'll leave behind too, to make new connections. Learn to recognize those people around you who don't drink, and seek out such people -- AA meetings are one place, but so might be a vegan restaurant in Boulder, or the health club!
