I was born AFAB, and started really hating being called a "woman" or "girl" around the time I turned 11. Thankfully, I was close to many queer communities and my parent is queer themself. I didn't stop using she/her pronouns until I was 15.
I switched to they/them pronouns, but I never really liked them... she/her pronouns I actively dislike, he/him pronouns I'm ehhh towards, and they/them I'm very neutral on. I've tried other pronouns, such as neopronouns, and the only neopronouns I felt somewhat positive towards (but didn't like a lot) were joke ones I said as a joke, and felt positive because I thought it was funny.
I know many people just don't use pronouns or gendered language towards themselves at all, but I don't want to do that either. So I'm just using they/them.
It feels a little sad, though. I wish I had an identity I could feel happy in instead of just ambivalent. The only time I think I've experienced "gender euphoria" is when someone asked if I was a boy or girl because they couldn't tell. I know it's not a universal experience, but I just feel put down by it.
