I can only add with my own anecdote. My son dated a girl when they were both 14. This girl had gender dysphoria. She was suffering from a lot of other externalities, but she swore she was a boy. Fast forward 3 years and she is now mature, optimistic, and very much a girl.

Culture seems to be going through a convulsion of sorts and it is taking an enormous toll on our young girls. They do seem to grow out of it, but the phenomenon is real.
