All I can think of is how desperate their parents must be.
I know 2 sorority women who are anorexic--they had started to become anorexic before they went Greek but it wasn't noticeable when they were first-semester freshmen.
They're both members of the same GLO at different universities and they knew each other in high school. I'm pretty sure that neither knows the other is anorexic, or in the same sorority. On the one hand, I want to tell them so they could support each other; on the other hand, I'm afraid they might support each other in the wrong way. Like the Ana and Mia way.
