You can look at it any way you choose. Gluttony is a sin. Addiction is a disease. Overeating to avoid dealing with feelings is both. Either way, hurting yourself does not please God. I've abused my body with food and disappointed God. I choose to accept His forgiveness and move on to do better. Weight Watchers happens to work for me along with prayer. Do what works for you. He loves you no matter what you do.

Oh, and don't forget to forgive yourself as well.
