What has worked for many with your dilemma is this.
Every time your hear or see the word "God", think of it this way instead:
"G.O.D." Good Orderly Direction.
Makes a BIG difference in the meaning and fits in with your way of living.
Also, please try at least 6 'different' meetings as meetings can vary so greatly before making a final decision about Al-Anon.
Love and hugs,
