Overeating hurts.

I have a lot of stomach pain, but for some reason I can't stop eating anyway. One would think this would be a great incintive to eat less, but I am a true addict in all respects. I guess I need to get addicted to losing weight again. But then I go to far. THIS IS SO CONFUSING and ridiculous. I just want to be 105-110, but when I start gaining weight I keep gaining weight, and when I start losing weight, I keep losing weight. I can't do anything in moderation.
