I live in a fairly small town, but we have an active AA community and there is at least one meeting every day of the week. Most days two or three. And several neighboring towns with meetings, also. I was lucky that I found great meetings right in my town pretty much right away. I went 2-3 times a week at the beginning, and I was also going to outpatient treatment 3x per week. Now I go to a meeting a week, most weeks. I'm 4 and a half years sober.
I understand what you are saying about feeling a little intimidated by meetings with a lot of established sober folks - but if you identify yourself as a newcomer, they should shift gears for you and go back to basics for a meeting or two. If they don't, keep trying to find a meeting that feels like a good fit.
