Breakingglass, please keep in mind that while you may find religious people at Al-Anon meetings it's not a religious organization. They talk about a higher power. But YOU get to determine what that higher power is.
For me, my higher power is the power of the group. The Al-Anon group has taught me so much and I've been able to do so much with their support. More than I could have done on my own. That makes it a power greater than myself.
I couldn't move a refrigerator by myself. But with three or four people it's really easy.
Remember, take what you like and leave the rest.
