Interesting discussion.. My depression preceded my alcoholism. I first dealt with (undiagnosed but it checks all the boxes) clinical depression at the age of 12, years before my first drink. To hear it implied that if you're sober and depressed you haven't adequately "treated" your alcoholism, is sort of like adding insult to injury.
The steps imo, are a good set of guidelines for living a happy and healthy life in general.. I still do not however (at least for myself personally) see the connection between having a spiritual awakening and the "cure" for addiction, beyond the concepts of control and non-attachment. Many spiritual people are addicts, many non-spiritual people are not.
