My friends think I have a serious problem. They have been to my head of year to tell her they are worried and I don't know what to do. I'm 15, around 5 ft 5 and weigh 98 lbs. My friends say I have all the symptoms of an anorexic, because I'm always cold and feeling dizzy and I eat no more than 600 cals a day. Do I have a problem, and what other symptoms do anorexics have?
