[ShesNotThere]

You've already accomplished a huge first step - you recognized that something might be wrong. You also worry about making your friends worry, and that's important. If you have an adult you trust, a teacher, doctor, parent, whatever, maybe talk to them about it. Explain how you're feeling and that you're concerned.

In the meantime, love your body how it is. You can always stay in good shape with a healthy, not empty, diet and exercise. Feel free to talk to anybody on here, including me, and good luck.
