flutter,
I think we are all nervous and worried the first time! you will probably hear the word hp and god, just sorta slide over it for awhile and focus on how you identify with the people. There are many athiests and agnostics and alternative HP people finding recovery in AA. you might check out the secular forum and post there too if you are interested. either post or pm about things as you start meetings and others can share how they deal with any problems that arise. And many find they go to a meeting, fit right in and love it from the start
