When you come out of this you will be a stronger, healthier person. You can say to yourself that you beat your disease, and know with all of your heart that you won't let it happen again.
Whenever you think that you can't and will not eat, or you will purge, whichever, find something to distract yourself. Read a book, watch a movie, call a friend, go for a walk/run, listen to some mellow music, anything. Just do whatever it takes not to give in to your disease.
People need to eat to survive, and you are endangering your body, which I'm sure you know. Whatever you think of your appearance, I know you are beautiful. Everyone is beautiful. It's a cliche for a reason, because it's true. You are beautiful. Don't forget that, and you will be just fine.
