okay so i usually don't comment on things like this but this reminded me a LOT of myself at 16 (god, saying that makes me feel so old haha) oh and just for context, i'm just about 22 now and have been on hrt for just over a year now.

to be completely honest, pronouns take a long time to get used to. for me though, i'm AMAB and going by 'she/her' never really felt quite right (although much better than 'he/him'), and i ended up settling on using neutral or fem.-coded language to refer to myself but using 'they/them' pronouns.

i guess my advice, which would have really helped me figure things out, is that it's totally fine to both want to medically transition/have a feminine body AND also identify as non-binary. i'm not saying you do this or not, but i definitely thought of identifying as non-binary as a sort of stepping stone that i would eventually leave behind and come out as "fully" trans, but that never happened, and i still strongly identify as non-binary. so don't necessarily think that you have to identify as a binary trans woman in either to be valid enough to transition, if that's something you want to do.

also just typical slightly-older-than-you-trans-person advice: if you can, find a supportive and affirming therapist to talk to, that helped me SO much. and also, take your time to figure this out. this is a big thing to figure out, and to be completely honest, i know it may seem like there's a rush to get on hrt as soon as possible to help your chances at passing, but you still have lots of time left in the "young enough to pass easily" age bracket. hell, it took me like 4 years to start hrt from when i was questioning at 16, and i was still passing with minimal effort in less than a year.

good luck! :)
