I've often heard it said that AA doesn't shoot their wounded. Most, if not all, of them needed more than one try to get it right. All it requires is a desire to stop drinking. Don't be afraid of them.
Sorry about your run-in with the law. I got a DUI a couple of years before I finally decided I'd had enough. While it was extremely expensive and quite inconvenient, it wasn't the end of the world. Hang in there, you'll get through it, but get yourself to a meeting and find a sponsor and work those steps.
