Can't keep food down and never hungry ?!

Not saying you are now, but did you use to make yourself throw up. For any reason. Because in this case, people that become bulimic at a certain stage your body kind of.. Forgets how to process food and you just throw it up without making yourself. I don't know if this is what's wrong with you, but you should see a Doctor. I would think you have by now but if not, just go to the doctor to have a talk. If by chance you do not want to do this for any reason, talk to someone close. But really even if you don't want to or 'can't' Just go see a doctor. Really, sounds like there is no other option. If this isn't an eating disorder or not. There's something wrong and you should go. Could be millions of things wrong.

As for a name, it's called Bulimia. Even if you used to but don't do it anymore on purpose. That's the disease name. Either way I'd go to the doctor straight away. If it's not you could have anything. The later you leave these things the less chance of fixing them.
Because if it's not Bulimia it could be anything. So I wouldn't know a name..

Hope this helps. Get well soon. :>

I'd say that you have bulimia. It's an eating disorder where your body can't process food and makes you vomit whenever you try to eat. If you're worried about your weight, your mind probably thinks eating anything will make you fat. You probably want to get checked out by a doctor. You should also consult a dietitian. You may even want to see a therapist. The choice is yours, but don't leave this untreated. A side effect... actually the main effect is a really, really skinny body.
