First of all, I hope Molly isn't reading any comments on LR these days. People are so incredibly mean and BTW, I'm naturally a sarcastic person but wouldn't piss on someone who a.) who has accomplished so much in her sport and b.) is openly hurting.
My suggestion to her would be to get away from the sport. However, it's so tied to her identity I'm not sure how possible that is. I am an eating disorder survivor, and I have a career outside of sport that I enjoy. I still run but being in my 40s, it's very much at the hobby jogger level. Plus, I was never as good as she was.
Second, a lot of people are discussing her trail race in the summer. That, to me, was just another example of her disorder in that she felt the need to run or move even if she was still injured or recovering from injury. I didn't read more into it.
If it's eventually revealed she was popped for Adderall, I'm not too bothered. It's not EPO and again, it's just another part of her struggle, and if you're eager to see I TOLD YOU DO, then you just suck.
Maybe this article is all PR but seriously, it's really hard to admit you're still struggling with mental health, eating, etc., to even your friends.
