MeShell, I'm not trying to get all "Dr. Phil" on you, but I believe you're right, it wouldn't be surprising if you started an addictive relationship with food because of your traumatic childhood experience. SORRY to hear about that! I remember my (evil) step mother would punish me by sending me to bed without dinner, that is not too bad but I think it's a bad thing to do, children need nutrition and there are other ways to discipline them.
I also have tons of crap in my cabinets that I don't even eat! lol
