Brittany Snow

I was 85 lbs. at my 2000 homecoming dance. But I wanted my collarbones and hip bones to show more. I'd feel my hip bones to make sure they were out. If not, I had more weight to lose. I lost my period until I was 17. I loved that. It meant I wasn't healthy, and I didn't want to be healthy.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
