I suffered all my life with this. I was bullied by most girls in school and never fit in with girls anywhere cause I was a freak for liking "boy things" like video games so since very young age I started growing this weird sense of "I'm definitely not a girl, I can't understand girls and I never fit in with them" while my brothers were my best friends. Puberty hits and my body changing and becoming different from my male friends and brothers felt terrible, suddenly boys looked at me in a different light when they were the only people who I felt comfortable being with. Eventually I trained my voice to become deeper for online gaming/calls and started binding my chest, I couldn't stand my physical body. I think video game culture at the time also played part, I felt like no one would take my video game skills seriously if they knew I was a girl. I wanted to be treated like everyone else, which was majorly boys in video game communities back then. I entirely quit going to swimming halls or any public beaches, I didn't want people to see my female body. It made me feel scared and ashamed.
All of that said, things are a bit different now. I'm almost 30 and all of this started around when I was 13. I've had a lot of time to experience things, grown different priorities about what's important, grown up. In the last year or two I had made the mental realization of why I always felt this way about my body. It was childhood trauma from being rejected as who I was, because I didn't fit a mold. Because I didn't chase boys like my peers. So I felt like I had to be a boy then. But growing up I started thinking, my brothers always liked me. They liked me because I was into things they also liked. I don't want to take away the sister they love so much. They love me the way I am, why not at least try to accept myself if other people do. There's no rule to what girls are allowed to like or be like, and if someone gives you shit you send them away.
I still struggle with my body and people in gaming communities knowing I'm a girl makes me anxious that they probably think I'm bad at games now. Cause all girls are, right? But when you plan to die, what does it matter. Do what you want, be what you are. I'm tired of living in that self hate and fear. The road to self acceptance after long years of brainwashing myself to be a man is not the easiest but I will die either way so I should just get anything out of life while I still am here.
