Only transitioning person I know suddenly had multiple falls like an elderly person, broke some ribs, and they wouldn’t heal. Has had other issues and resigned from the dream job because the health issues are out of control.
That one is still in denial as to the cause.
I honestly believe that no one is born “the wrong gender”. I believe something in their very early life messed with their mental health that pushed them into that mindset. The same with gays.
