I haven't told my parents or my grandparents either.

My parents are not accepting of MI, and one of my grandmothers has dementia, so idk if she'd really understand (not that I would have told her if she was mentally healthy, but I'm just saying it's not an option). My other grandmother wouldn't understand either. "Huh? What's that?" is what she would say.

Also, my dad can be an idiodic asshole sometimes. He doesn't know how to keep his mouth shut. So even if he *were* accepting, he'd tell the whole world.
