When i was a very active member of alanon I did identify as a christian much more than I do now. But the religious based meetings freaked me out. I KNOW they say you can find a higher power in anything. Mickey Mantel, Mickey Mouse, a tree--what ever--but I dont understand that.
My higher power was simple. I wish that I could point you into another direction. I know alanon is not supposed to be religious, but I know many meetings are. If you CAN personally identify your higher power as the universe or "the way the world works" I am SURE you could do it when you are on your own time//or maybe even in a meeting? .
I ended up finding a very non religious meeting in my area (yet in the basement of a church) and felt much much more at home there with those who did not identify one bit as christians. I am sure there must be athiests and agnositcs who can give much better advise, but here a starting point.
