I would say that if anyone out of all of those involved in this weird controversy is "mentally ill," it's the otherwise uninvolved outsiders who insist on making an issue of someone else's gender identity.

I've never even understood how this is an issue in the first place. I can see how gender identity could be significant when one is evaluating a potential sexual partner, since one would likely have some preference(s), but beyond that, I've never understood why anyone even cares. What possible bearing can it really have on anything?

So as far as I'm concerned, if somebody does concern themselves with it and try to oversee it and legislate it and control it, in spite of the fact that it has no real bearing at all on their own lives, there must be something wrong with their brains.
