I went kinda fast with this. I think I'ma just go by Autumn. And use She/they pronouns.
I thought about it a lot and I think this is what I should do for now. It seems better than rushing to into something I don't know yet. So, until further notice, she/her and they/them. Don't really care which. And I'ma keep my name, it's kinda neutral too. (Plus I like the name.)
