Did you read the article from Bleacher Report that is being discussed? Here are two quotes:

"That anxiety that I had around having to make a certain weight and look a certain way…"

"I feel that anxiety and depression again every time I'm on that campus"

Here is one more:

"I felt like a burden to the teachers. I lost my appetite, and I would do extra workouts just to feel the pain. We weighed in once a week, and because I wasn't eating, I was always underweight."

That does not sound like the behavior of someone who was well and happy.
