There are a wide variety of self help groups based on the 12 steps, originally developed in Alcoholics Anonymous. Here are a few:

•    For people seeking to manage their spending and debts
     Debtors Anonymous is a great resource
•    For people working to overcome eating issues, there is
     Overeaters Anonymous
•    For help with incest and childhood sexual abuse, the
     NYC branch of SIA has meeting lists for the tri-state area
•    For help with issues such as grief, anxiety, low self-esteem,
     panic and other emotional issues, there is Emotions Anonymous
•    For help with couples issues, there is Recovering Couples Anonymous.

     the only requirement for membership is a desire to "stay committed in
     loving and intimate relationships"
