Gender envy

I'm so tired of getting called a girl, I'm done with it. I wish people would see me as a boy, I'm done with not feeling like myself. It's not fair. I am a guy why don't people just see how I am? It sucks, I hate crying in my bathroom for hours about how I'm not truly a boy, sitting on the damn floor while blood runs down my arms and thighs. Why can't I just be a fucking boy! I just want to be viewed as myself not who I used to be
