LRC is such a strange place.
This is sad news and it sounds like Molly is struggling with things again. I commend her for making this decision. I trust that she has an injury. I also believe that some demons from her past have resurfaced. Mental health issues are just like substance addictions. It is an ongoing and lifelong fight. In my estimation, she is being honest and is trying to do the right thing by seeking permissions up front. ADHD, OCD, and depression all go along with ED issues.
Give her the space to fight whatever battles she needs to wage at this time. Speculating that she is covering up a PED positive or casting her as a weak individual is neither helpful nor fair. If this were a male athlete, 90% of you would be supportive and praising their bravery.
Best wishes to Molly - get well! Best of luck to Keira in Eugene!
