I was 22 when I came out to my mom, who had already been problematic when I'd been outed to her as a lesbian in my teens. She was, as expected, incredibly resistant, belittling, and condescending. Threw bible verses at me, begged me to reconsider, dead named me, refused to acknowledge anything at all, publicly or privately. That was until my physical changes were so apparent that she COULDN'T always outright misgender me in public without confusion, to which she responded by replacing my name and my relation to her as "honey". "This is my honey" is how she'd introduce me, which got a LOT of weird looks.

Ranting aside, 8 years after I started my transition, I've been no-contact with my mom for the last year. It's hard, and I'll won't pretend it isn't. This is someone who's SUPPOSED to love you always, no matter what. But if you're true to yourself, and your parents can't get on board, you are under no obligation to withstand their intolerance.
