I do not think that a person fails AA or that AA fails the person. For some it works very well and for others it's not a fit.
If you think AA is not for you try something else. But do keep doing something to feed your recovery. I have observed folks who say that AA is not for them and so they stop being active in AA and stop working on their recovery. They do not look for a replacement recovery program. That is not a recipe for success.
