I understand how you feel about AA in some ways. I got sober with the help of AA fifteen years ago, I believe in the principles of AA, I try to work the steps as best as I can. I also think there are a lot of good people in AA but I know what you mean about certain members doing other's inventorys. I am fifteen years sober and I stopped going to AA some 12 years ago for about the same reasons you dont like it, I believe one should find their own program, whatever works for them. My father has been sober 45 years and still goes to at least 1 meeting a week but he lives AA with this in mind at all times: Principles before Personalities.
Do whatever works for you, the important is that you stay sober and live a happy life. I, too, suffer from depression and last year going through a really bad bout of depression I tried to go back to AA and came to the conclusion that I am better off going to see my therapist and trying to live the principles of AA the way I understand them, I have too much trouble with the Personalities.
One day at a time...it works!
