The New Codependency by Melody Beattie

The New Codependency is an owner’s manual to learning to be who you are and gives you the tools necessary to reclaim your life by renouncing unhealthy practices.
Each section offers an overview of and a series of activities pertaining to a particular behavior—caretaking, controlling, manipulation, denial, repression, etc.—enabling us to personalize our own step-by-step guide to wellness. These sections, in conjunction with a series of tests allowing us to assess the level of our codependent behavior, demonstrate that while it may not seem possible now, we have the power to take care of ourselves, no matter what we are experiencing.
