So far only my mother's side knows, my grandmother seemed slightly surprised at it but accepted it, she told me that as long as it makes me happy she'll be there to support me through it. My mother, well, her reaction surprised me, I expected her to be at least somewhat surprised, not the case, she started explaining to me how some people are born the wrong gender and asked me what took me so long, so she certainly expected it and even admired she had had thoughts in the past about if she was born the right way herself! Which I actually find slightly humorous because she's always said she's "80% woman, 20% man" and I can recall her saying this since I was a child, I mean, after all, this is the woman who taught me how to hunt and how to shoot so, I guess it kinda makes a lot of sense in hindsight.
My father's side doesn't really know, and I don't plan on telling them yet, I already know how they will react and the only one from that side of the family who would have accepted me is no longer with us, my father's side of the family isn't really that important to me, relations with them have been shaky at best and violent at worst in the past, more less I could care less if they accept me for this or not, they already don't accept me because of my religion, my views on life, my independence, my general personality, my likes and dislikes, the fact I don't let them dictate my life, so, what's one more thing about me that they don't accept? Something tells me they'll expect it but still be against it because "You will always be how you are born and raised." according to them, so eh, hell with them, can do this with or without that side of the family.
The few friends I have, who I'm including them cause to me, my friends are my chosen family, are very supportive, ok, they crack jokes bout it now and then, but that's just how we are, and it's not like I don't crack jokes right back at 'em, after all, if ya can't laugh at yaself, what can ya laugh at? In truth that acceptance and humor helps me through a lot, amazing how much a good laugh can help ya get through the day.
