What can the doctor do for me.

honey, you need to eat. when you dont eay, your organs begin to shut down. i really do believe you have an eating disorder. please go see a doctor, they can give you the propor counseling that you need to be healthy again. i know how it feels to to want to look like those models, and want to feel beautiful in that way, but you are not losing weight in a healthy way. the best way is to eat 5 SMALL meals a day. if you deprive yourself, whatever you eat later on will stick to you completely and cause you to gain weight. please seek a doctor.
