I am also an alcoholic and long time runner. You've gotten some good advice - and some less good - so far.
I haven't had a drink in 30+ years. What worked for me was (and is) AA. It saved my life. Is it a cult? No. Do you give up your ability to think for yourself when you join? Hardly. Some groups (and individuals) are more dogmatic than others though. I try to avoid the extremists. Within AA there are so many different types of meetings and philosophies that there is a good chance to find a place where you fit. The "problem" though, is that one has to be beaten down pretty far for AA to work. If things are just bad, or horrible, you may not be motivated enough to get a sponsor, work the 12 Steps, etc. My experience and my observations over the years are that it has to be mind blowingly bad, pitifully and incomprehensibly bad, just an emotional degree or two from blowing my brains out bad.
I don't always like what I find in AA. I just moved from LA to PA and have had to find new meetings, new friends, etc. I've stumbled across some good meetings run by decent and caring people with little to no self serving bullsh*t. I've also been to some terrible meetings featuring ill tempered individuals and at least one self-serving guru who had managed to brainwash a couple dozen "followers". Very sad.
AA is a microcosm of life. If you're not convinced it's bad enough (sounds like you're pretty close), keep on drinking. When it gets very very bad, give AA another try, and try several meetings. Best wishes to you.
