Just want to point out codependency--especially if you read Codependent No More--is not about being dependent on another person. That is dependent personality disorder perhaps.

Codependency is better described IMO as secondhand addiction. It was coined to describe the symptoms of people who live with alcoholics and other substance abusers and the destructive coping patterns they use to survive in the addict's wake. The codependent does not depend on the addict. In fact closer to the opposite.

Upvoted just for mentioning the book though. It was life changing for me.
