I don't know what to call my identity (nor what it is exactly)

So my gender is weird. So basically most of the time I'm a trans girl, but like not fully a girl? idk, hard to describe. But it also changes - I can sometimes be "more nonbinary" or more close to fully girl, sometimes I even am fully a girl. I've settled on girlflux and transfeminine nonbinary, but depending on the occasion I might call myself just a (trans) girl or an enby. But nothing seems to fit perfectly and I still am not 100% sure that that is what my gender is. I definitely know that I'm not cis and that my gender is closer to being a girl that to boy most of the time.

I felt like I had it all figured out when I thought that I was a binary trans girl, and then again when I learned about the label girlflux, but now I'm confused all over again. I also kinda don't feel valid, idk why every time I think about being nonbinary I feel like that.
