I’m guessing Hollys parents haven’t stepped in because of the idea that an eating disorder is rapidly losing weight and not eating, so if she is eating (although restrictively) it can be fairly easy to cover up, especially as she’s vegan. But she’s 23 right? They might just feel like it’s not their place to comment, or they’re oblivious. That said, I’ve been in holly’s place before and my family were constantly expressing worry over my appearance and actions until I did something about it so it’s kind of a shame to see nothing happening.
It’s ridiculous that she’s sharing what she’s doing though. She went on 2 walks, imaging they were pretty long, and did some stretching and all she ate was some mango, some porridge and some pasta/bean/veg thing. Good luck to her running the marathon, I cba with her anymore it’s a recipe for disaster.
