It has nothing to do with the doctor's charts or how much you actually weigh. You're screwing up your chemical balance losing weight as fast and in the manner you are. And you've already said you're like an addict and don't want to/won't/can't stop so "time" is not an issue either. That's like saying a crackhead is all right for awhile. Only as long as the money lasts and then they're totally, utterly screwed. How can you not see you'll have troubles like zombiette did? Get to a therapist, you're not "special"/different from the rest of us. It's getting out of your control and you actually have less time than your body will grant you. An airplane in a dive "could" pull up before it smashes into the ground but not if it can't get out of the dive.
