It sounds like you need to talk to a psychologist/therapist who specialises in gender dysphoria. They would potentially be able to help you arrange your thoughts on the matter. No-one is going to be able to give you a definite answer on the internet and nor should they. I can tell you that I am going through the hatching process at the moment and am experiencing something similar. I’m a long way past puberty (old enough to be your parent) and the thing that bothers me is that I didn’t adress this sooner. If I had investigated my gender identity at your age I might have enjoyed my adult life and not spent every day depressed and angry at everything.

It’s possible that you aren’t transgender or that you are. But even if you aren’t it’s still useful to know that. If you know any trans girls IRL you should talk to them about it and see if your experiences align with theirs. Also, I don’t know about your family situation or political environment where you live, but if you could see a therapist, it wouldn’t hurt. Just make sure you address it soon because you don’t want to spend the next few decades of your life miserable. Again I’m not saying you are or aren’t trans. Only you can figure that out.
