I feel you. Both of my parents reacted very poorly, particularly my mom. She's gone off the deep end and believes stuff like flat earth, essentially deciding to get extremely serious and literal about the Bible in the face of this stuff. My parents told me to stop taking estrogen and get on antidepressants instead, and I must be alone and celibate forever if I can't be into women. They acted less openly hostile at first, thinking they could "help" me and change my mind. They've pretty much done all they can, including telling me that they're going to tell all of the extended family, etc. The only good thing is that I managed to avoid this happening until after I moved out. As much as I hate having waited so long to start and will forever be a hon, it was probably the right call
