Oh boy do I know the feeling of just understanding from a very young age that you're wrong/different/broken.
It is then very disconcerting to have somebody (or a video, or an article) enumerate a dozen different things about you that are the exact things you've been hiding about yourself (and often to yourself) your whole life. It feels very exposed, very vulnerable.
I can't speak for everybody, but it was a trial for me to take an honest look at myself and accept that, yes, these labels describe me. And then that exposure that was so frightening becomes a freedom. That label which felt like it was going to be a straitjacket is actually the best fitting, most comfortable clothing you've ever had.
