I cant stop looseing weight? HELP!?

go see a doctor, you may have a virus that is affecting you and causing this. There is a high likelyhood that it is due to sickness if you are throwing up/have diarreah but even if you don't have these symptoms, it still may be a disease. GO BEFORE ITS TOO LATE my friend lost her period and all her energy and got reallyreally sick from some virus or something so go see a doctor right now!
