Im so confused about my gender identity!

Hello guys, first of all i hope you are fine. Also, I hope that you can help me or give me some advise. But from the start.
I'm female and in my childhood I never questioned anything. I played with dolls, my parents made me wear dresses and I always had long hair. I knew nothing about any non-binary gender identities, probably because I haven't been on the internet at that time. So, when puberty started to hit me, I didn't like it when people told me: Thats nothing a girl would do, and stuff. Also I got on the internet and became more independent thinking. (I'm sure this wasn't right english grammar, I'm sorry). And then, when I was 14( Im 15 by now), it was more and more like ... sometimes it really sucks to be a girl. I never wanted to be a boy though. Then, I cut my hair off. It was one of the best decisions in my life. I felt so, so good about it. I started to have these days, when I was shopping and thinking about if i would pass as a boy. Some days I would be completely a girl again. Some, i don't know, anything in between. I got to know a transboy and he told me about binders and stuff. I did some research and thought it was kinda a cool thing cause my boobs freak me out so much sometimes. But I was too afraid of buying a binder, so I bought a two-size-to-small sport bra and omg, it felt so good. It is not a big difference but I thought its amazing. There were more days I ran around with boy clothes and wondering if i would pass. But im so confused because... I don't feel like I want a penis. I don't feel like im trans... I am just so confused about everything. A couple of days ago, I went to a concert with my mum and we met an old acquaintance of her and she said "oh, thats your son, right?" and my mum was like omg, noo, she's a girl! And I was like so happy and even more confused at the same time! Also a mate of my dad once told me I'd look like a tomboy, what made me happy as well. I dont know even why.
So, thats it, basically. Can you help me?
Thank you! :>
