I just got back.
It went fine, no drama at all. Some people had already figured it out, based on some things I'd mentioned at the last family session (New Year's.) Mostly, the reaction was, "good for you." A few people asked about my transition and we had some nice moderately deep conversations. Some people managed to always call me by my future name, including some people who I hadn't expected to pay much attention to it. With the rest, it was mixed, and from what I could see what misnaming there was was inadvertent. Keep in mind, this was a work weekend, so people were running around finding and doing work projects, plus they were trying to sing Handel's Messiah with whoever showed up to sing. So they had bigger things on their mind than me trying out a new name.
But each time someone addressed me as "<new name>", it was a pleasant jolt. I'm definitely not at all used to hearing it, but each time I do, it gives me a warm fuzzy feeling that my new sense of who I am is being validated. It's like everyone else is having an easier time getting used to it than I am.
Since there were a few teen-agers there, I got to thinking about how they say that when we do HRT, it's like a second puberty. Well I now think that, even aside from the hormones, it's a lot like a second teen-ager-hood. My whole sense of who I am is getting up-ended, I'm insecure about almost everything, and my emotions are going everywhere.
We got home about an hour ago, and as I was ferrying stuff from the car to the apartment, one of my neighbors called me by my old name (the one that I still use most places), and I felt so disappointed. Especially since they're really nice neighbors and I'm sure if I ever came out to them they'd be supportive and do their best to call me by my preferred name.
I guess I'm getting to that super-uncomfortable place where I'm still scared to go forward but I realize I can't go back. It's like getting 20 meters down a ski slope and suddenly realizing what they mean when they rate a ski slope double diamond.
