A girl that eats more than most

[manielebo]

To start this off I ride horses and go to the gym and am in high school. I eat more than most girls and it makes me feel insecure so I started to eat less in front of people. An example of this is if I'm hanging out with friends and we eat pizza they eat one to two slices but I have to eat five to be full. It makes me feel uncomfortable and insecure so I was wondering if anyone else experienced this?
