I think she's brave. I also think people should be able to explore different aspects of their character in public without being harassed, mocked or labelled either mentally ill or vulnerable. That, sadly, isn't the society we live in.
She tried something and it didn't work for her, or bits of it worked and other bits didn't and she needs to move on again. I think she's fully grasped "fluidity" at least, in a way other people haven't grasped.
I also think that the rigidity of gender roles is a big part of why they are damaging- if there was more ability to be fluid, both within roles and as an individual person, a lot of people would flourish more. Fluidity over time, in response both to self and to changing circumstances is essential to evolution and adaptivity.
