How old were you when you began questioning/considering you weren't "normal"?
I'm in my 30s and almost all at once feel like I'm not sure what I am in most demensions and struggling to figure out what I feel about anything. I've been married, happily for a while, which adds a little to the confusion.
I'm not sure how old I was, I just remember where I was, and we moved away from there when I was 6.
My family wasn't outright transphobic or homophobic, but they were generally insensitive and talking to them about it didn't feel safe. I also reasoned with my limited knowledge at the time that there probably wasn't much that could be done about it even if it was accepted.
So it took until I was 18 or so before finding out about other trans people, and about HRT (this was many years ago, before the current awareness)
