Thinking about asking my mom directly to use they/them pronouns for me. She used them for a little bit after I told her about my gender cornfusion but she stopped doing it after a while. I don't feel ready to use she/her in person (online it's easier because it's not connected to my physical representation) but this would at least cut out the discomfort of being called "he" all the time
also working up the courage to join a local-ish queer discord. I just don't wanna join and find out it's like 5 random people and they're all libs
I hope your Mom is cool! I think a gentle correction sometimes is good too, I do that with my parents sometimes and it helps.
You totally should join your local server. Probably a queer discord is one of the most leftwing spaces out there, so you might find a comrade or two. And even if not, it's always good to know some local faces.
