Yesterday I fought I was a demiboy with part girl but today in confused I have no clue what my gender is. I think I might be nonbinary I'm not sure aaaaa I am confused
You don't need to label the other part if you aren't sure what is it.
But if you really want to, do you think the second part of your gender could be both girl and NB? Something in-between the two? A girl in a non-binary way? An enby in a girl way?
Have you taken a look at labels like nymgirl, juxera, quella, etc that express a nonbinaryness that is also (in) directly related to girlness?
Then, I'll suggest taking a look at labels like xirl or girlby/engirl, that express all possible intersections between been a girl and been non binary. Maybe they could work for the other part of your gender.
