I really see AA as a huge melting pot for troubled souls.
You're correct. The same thing is true of Alanon.
I'm a recovering alcoholic in my 22nd year and I'm also codependent so I've been to both. Many alcoholics come in via Alanon. AA and Alanon are opposite sides of the same coin and it's no coincidence both use the 12 Steps. Alcoholics are addicted to booze and codependents are obsessed with alcoholics. The good news is both programs work if you're willing to do the hard work of recovery.
