Unless you get psychological help ASAP, you will die in a few years from what you are doing, without question. No ifs or buts. You will starve to death. You meed at least 1200 cal a day and normally a lot more more for a growing child just to keep your body functioning. Continue as you are, you will never get a period, never grow, never be able to maintain a job, never have a normal relationship or a family. Those are the simple, hard facts. Eating disorders kill. Your internal organs will collapse, your heart will not eventually be able to take the strain.
