Why such a stigma against anorexia?
Because it’s a horrible, life-threatening psychological disease.

Why such a stigma against attractive, well-proportioned young women trying to just lose those damn five pounds? Because it’s a shame to destroy something beautiful. Especially when it’s yourself. Because it’s a shame not to realize something is beautiful when it is.

Jennifer, I’m willing to bet that the people who so flippantly challenge your efforts to lose weight and who do so in a way that makes you feel like you’re being belittled are too insecure to tell you you’re lovely just the way you are, and try to make light of their worry by comparing you with mental illness.

Or that behind their breaths, in the places that must know beauty, they’re just hoping you know you’re beautiful, too.
