This is so familiar to me, I hope you know you aren't alone in feeling this way. Like an above poster said, it's addicting. When you first start all the compliments mean the world, I loved being the desirable one, the skinny one, the one all the other girls envied and hated. But even with the good, the bad comes too. The fatigue, the health problems, the insomnia and insanity. But it is so very hard to stop when it becomes your everyday routine, the only thing you know.

Please please be careful. You may not want to stop but it is a dangerous road to travel down. Know your limits, and know that people care about you.
