Nice! For me it's my friend group, my Math teacher (actually the first person who consistently used it) who even uses it during the lessons, my parents and some other people. Damn, even that conservative Christian classmate asked me if he should call me Raine or my deadname, he didn't even ask why, he just asked.
Things are going pretty well with social transition (even though I'm still extremely scared of coming out), and I hope it gets better for you as well. I think I have an advantage, I live in one of the more conservative places in Germany, but it's probably still better than US.
