If she was even a little bit serious about ENDING her eating disorder, she would get off IG and stop making youtube videos, but she won't.
She is not even the only person who does this. She is consistently making posts that "Center" and emphasize her body (full-body camera shots from all angles, pictures in workout gear and swimsuits, showering topless with 1inch of clearance. ZERO shots of her mountainous environment or any scenery) because there is positive attention with this.
Then when the orthorexia comes back to bite (stress fracture, running like crap, getting dropped) she suddenly remembers how to point a camera at just her face and talk into it, seeking pity and a high view count with a clickbait title.
Just an incredible amount of selfies and documentation of what she looks like every single day. It is a practice of arrogance and narcissism. Doesn't matter that she cries about it every couple months. She is proud of her body and is happy to show it off until her leg breaks from running for the 10th time.
