What Should I Do?

Your friend is correct. You have no option left but to consult a doctor. You need serious medical care to get such diseases cured early. Hopefully, you will consult the Doctor and give us a feedback. By that time take adequate rest and eat healthy food.

In anorexics, food consumption can be monitored and controlled, while bulimics see purging as a form of cleansing, getting the bad out. Food can be one of life's greatest pleasure. For someone with eating disorder, food can be a curse. If you are victim yourself, take yourself to a counselor, and fast.
