shop around the aa meetings....it does help if you relate and chicago should have a huge variety of meetings. I do AA and don't believe in god in a biblebelt community that is fairly small...but it is going well for me.
And as has been said, look at other options..SR, liturature that helps you, lifering, check out the secular recovery and secular 12 step threads...post here and pm people if you think they have something you can use.
I was trying to put off treatment till I had a vacation from work....didn't work....ended up inpatient for 4 weeks as there just wasn't another way to do it or any time left to wait....
Lots of people here, lots of ways to do it....Glad you are here and alive!
