Co-Dependents Anonymous (CoDA) is a fellowship of men and women whose common purpose is to develop healthy relationships. CoDA is modeled on Alcoholics Anonymous (AA) using the same twelve steps as AA with the substitution on one word in the first step, "We admitted we were powerless over others" (not alcohol) "-- that our lives had become unmanageable." It was founded in 1986 by Ken and Mary, long term members of AA in Phoenix, Arizona, who felt a need for an AA-type fellowship to cope with their codependent behaviors.
