Pretty sure it was the other way around: Simone said after TF that she was stepping back for mental health reasons. She laid the foundation for this narrative, not the media.What appears to have happened, however, is that commentators immediately started characterizing it as a “mental health” problem Simone had and I think Simone just kind of went along with it for whatever reason.
Based on what she’s said, I assume that Simone understood her twisties to be a manifestation/consequence of mental health issues she was struggling with at the time. I don’t think we can ever definitely prove (or disprove) this link, but honestly if that’s what Simone says, I see no need to contradict her. We all saw her struggling at Trials, and crying after a sub-par beam routine, so it’s not as if there is no other evidence of mental health struggles around the same time.
