Glad you found a meeting to suit your fears.
Fear of being recognized at a meeting kept me from going for a long time, too.
By the time I decided I needed the help, any illusions I had about how effectively I was hiding my drinking were just that - false illusions. I went off to treatment, and when I came back home went to my first meeting excited to get some help with my alcohol abuse. I now go to meetings because I really want to; often they're the bright spot in my day.
I also realized anyone I see at a meeting didn't just walk in because there wasn't anything good playing at the movie theater. They are there for the same reason I am - they have a desire to stop drinking.
When I was in treatment I remember a counselor telling us a good response for anyone who might find out and give us grief over going to rehab, or to AA/NA meetings - "I went there/go because I had a problem and I dealt with it so that I don't have to live like that no more."
