I'm 5'5 and now weigh 104. what is the criteria for being hospitalized for anorexia? i'm terrified of seeing my physician in a few weeks.

Whoa: This is slim but not dangerously so, bmi 17.3 for what it's worth, and while the bmi gurus will tell you this is "underweight" there are plenty of healthy light-boned track stars who are slim as you are. Your acknowledge depression and that you are receiving multiple meds for your emotions. What you need most is a physician that you see as a friend and ally against what might be dangerous.
