I'm kind of in the same boat. I've come out to my mom, but not to my dad or sister. I am on medication for a few mental disorders and they just don't understand them. They think that it's "all in my head" (pardon the pun) and that I just want attention. So, how do I come out with something like this?
I feel you, Malachite (I love that name, btw, it's a beautiful stone). I'm just trying to be true to myself and I hope one day I can be true to my family as well.
