I came out pretty darn publicly on FB. I did block a few people from seeing my post about my transition, until my partner was ready and able to explain to those people what was going on (his friends, more than mine, though somewhat mutual)
I also changed my pronoun to male, changed my name to what I'm going to use as my legal name when I scrape the cash together, ect.
My mom is steadfastly ignoring it. One of my siblings doesn't care, and is just, there, I guess. Her words were "I don't judge, I only support" so that was nice. My younger brother and older sister were upset I didn't come to them before posting it so publicly on FB, but my older sister has come to me about it, and expressed that she supports me in my decision. My younger brother and I used to be closer, but he hasn't said anything about it really.
Thinking of that, I really do need to sit him down and have a chat with him.
My older brother I only have limited contact with (not by choice either, but I don't want to really go into that) I know he would probably be vehemently opposed to it, but would eventually get over it, because he loves me.
My mother doesn't know I'm on T, but with the facial changes and voice dropping, she's starting to pick up on it. She doesn't want me to use hormones, but it's my life, is how I feel about it, and I'm going to do what I need to do to be comfortable in my own body.
My father is... weird, and I'm autistic, (high functioning, but still have a lot of sensory issues) and I suspect he's also autistic, but he's been ignoring it.
I think once I change my name, legally, it will become more real for them.
