Is this a phase or do I really feel like this is right?

So.. Biologically I was born a female. I've been thinking about my gender for a good while and I've only recently, as of maybe 4-5 months ago, started to understand the concept of being trans. When I was in 7th grade I had the biggest crush on a girl. I was like "okay..? so I'm gay. that's okay, great, I figured it out." That ended and during the start of 8th grade I liked another girl, but it was different. My desires weren't in the perspective of a female. Backtrack to when I was younger, I can think of so many times where I wanted to go outside and play in the dirt and ride my bike with all the guys. I would refuse to play with dolls and when I did have to I ended up playing as the male one. When 6th grade began, I started to get questioned by the girls about why I wore the clothes I wore and all I could say was that I was too lazy to try; I was just wearing what I liked to wear.. jeans and tshirts and vans. All throughout middle school it was the same. I never thought anything of it until my first crush on a girl. Now, back to 8th grade. I wanted to be with that girl but I wanted her and everyone else to see me as a masculine person, I just didn't know it. I started doing little things like standing up straighter to look taller and not shaving my legs. I would always try to become friends with the guys and get in with them. As of right now, it's summer and I want to be able to wear shorts and a tshirt with short hair and my facial hair and deep voice coming in. I desire to become taller. I've attempted to shave my face. (It never works as well as I'd like.) I told my best friend my thoughts and she's all for supporting me, but I told the girl that I used to like and she called me sick and "a transgender". I still want to be seen as a male but after that I'm scared of other people's reactions. I don't want this to be a phase. I want to be right about something for once but now I'm not sure. I find myself trying to talk to a boy. I want to try to like him. I don't know if it's me now identifying as bisexual or if it's me trying to convince myself that I'm not a male. Can anyone make sense of this? Is there a possibility that I'm wrong?
