My stepsister had an eating disorder a year or two ago. She got pretty bad and had to be hospitalized. Luckily, it was just a phase. She's back to her old self again.

I can imagine eating disorders affecting your brain. I know when I don't eat right I have trouble concentrating. I'm sure if your malnourished enough, you'd start going a little crazy.

It's so wierd how they can look in the mirror and see something totally different then we see. Christina probably thinks she looks fat in that dress or something stupid like that. They don't even realize how sickly they look.
