Back stories are fine. But you need to be concerned
most with giving yourself positive traction to use for going forward.
I have no religious convictions for any "higher power" stuff, so that was of no use to me in AA. I dare say a great number of us who get and stay sober don't have religious faith. But that's covered even in the Big Book. You can use the ordinary psychological underpinnings of the "steps" for your own purposes, as Bill W. describes--instead of the "Higher Power" of the traditional God, you use the group strength served by your support system: your group, counselors, sponsor, therapist, friends, family--that network of support that you construct for yourself so that in a crisis you are not alone.
Again, I am concerned that you seem to be unable to travel any new ground. If you are willing to use only tools that have worked before, you might suffer no new failures ... and probably advance no further. But I wish you the very best.
Please invest your best effort into madisgram's list suggestion.
And remember: You are doing all this as an investment in your future.
