Should we sympathise with anorexic teens/models?

I feel bad about modern society in general when there are people who are willing to avoid necessary functions of life for the most superficial and unecessary reasons you could think of. But, I don't feel bad specifically for them, there are wayyy too many people out there with worse things going on (ie everyone) because if you look like ****, that's fixable, being a kid that's too weak to stand up in a third world country that has absolutely nothing isn't.
