What would I look like if I were bulimic and anorexic?

So, I don't want to hear the fact that I need to go to a mental hospital or anything along those lines, so please don't write those anwers. I want to know what I would look like. I mean, some people say that if you are bulimic, your body gets thin and whatnot, but your face and neck chub out. How true is this? How long would it take for me to be 110 pounds if I weigh 150 pounds now at 5'4"? If anybody can answer these quesetions without telling me that I shouldn't be anorexic, or bulimic, or anything like that, I will chose you as best answer. I promise.
