I felt the same way about 12 steps (too god-centered). I found a "Families Anonymous" meeting I like. For me, letting go was key. I was hanging onto the fact that there may not be a god/higher power as much as the "religious" folk were clinging to their god. My RAH has been sober for 8 months. THAT is a miracle, an achievement, something I could not imagine. I don't care if there is or isn't an hp. The importan tthing is I am working on being a better person (the alcohol is almost irrelevant at this point as it was only a distraction of deeper, underlying issues for me, the wife, and for my RAH.
I decided to let go about the issue of an hp. If the 12 steps work for you, awesome! If not, I hope you find something that does!
