You have done the leg-work. You picked your meeting. There is no reason not to go ..... except fear. My first time, I drove to the parking lot, Sat there for a bit, and left. Fear. My second time, I actually went in and was glad I did. I won't say I was 100% comfortable, but it made me laugh at my first failed attempt. Go and report back on how it went. Nothing to fear. A meeting at AA is a safe place to be.
