I'm struggling about what gender i am. I don't feel like a girl. Neither a boy. But i also don't feel like non-binary. The closest to how i feel is girl. But not really.
Sounds like Demigirl, Genderfluid, or Genderqueer/fae
But take your time, I may be wrong, you know you better than me!
Try looking at the Agender page, Cassflux and maybe Demifluid (static being agender, fluctuating being girl or demigirl)
Just remember you know yourself better than I do.
