Liz ~ I would highly recommend you calling the churches in your area to see if they are or will be offering a class on Untangling Relations, a Christian perspective on codependency. It was the best thing I have done for my recovery. It was a 14 week class, workbook and all. Although I liked Codependent No More, I found this book far more helpful. Like many codependent Christians, even my relationship with God had become warped.
The clicks came so fast and so powerful, I was shocked at how much I didn't know about myself. It was very empowering!
