I think what you are feeling is normal.
I was always a tomboy and for about 6 years, from age 13-19 I though I was transgender. I wore mostly all boy clothes. Had no interest in girly things, still don't. Ordered binders for FTMs of the internet. I wanted surgery and hormones. I came really close to starting hormones. I finally noticed that it was just my mom making me feel that way. Ever since I was little I was never feminine enough. I wanted a skateboard. She wanted me to play with dolls. She forced gender stereotypes onto me and made me feel like I was the wrong gender. She has been trying to get me to have a breast reduction and it wasn't until then that I noticed how messed up she was making me. I like video games, drumming, extreme sports, and what not. I don't need to be a guy to like the things I like. She makes up crazy rules that woman have to live by. For example. Only guys can wear sneakers in the summer or with shorts. You have to always have all 20 nails painted. You always have to carry a purse. I also have PCOS and got horrible periods since I was 11. That didn't help at all. I now take birth control non stop so I don't have to deal with that. I get about 4 periods a year that way. The biggest thing for me was realizing I didn't have to fit anyones view of what a girl should be. There isn't a role I have to follow. The clothes for girls suck now. Everything is so tight. I am in the normal weight range for my hight. I could gain 10 pounds and my BMI would still be normal. But very few tops for girls fit me. My DDs are the biggest problem. Everything is made to make you look "sexy" and show everything. It is really hard finding modest clothes. By todays view of thin I am fat. I remember in high school girls talking about being 94 pounds and how 90 looked to anorexic but 96 looked fat. I was 90 pounds when I was 10 years old. These girls were about 16. A little boys Medium is bigger then a girls XL. I noticed this the other day when there was a misplaced kids t shirt in the womans section.
