Ok to give her the benefit of the doubt, you don't need to be underweight to be diagnosed with anorexia(ie: eating significantly little). Maybe she just developed the symptoms recently?

That being said, as someone who knows a couple people with actual anorexia, the extremely skinny frail kind, she doesn't have anorexia lmao. Also, most people with actual legitimate eating disorders don't go to social media to tell everybody.

There are people with legitimate, diagnosed eating disorders and then people with quirky "eating disorders" because they think it is cool to have one.
