How I got always rejected

At my school, lots of girls always reject me when I want to be their friend. Not only that, they always make fun of me and do things a bully does; saying I stink and that I’m not a clever person. It’s true, I didn’t get good grades always, but I’m the smartest in English and Science. However I’m always missing my mother and too scared to go to school. I also didn’t want to tell my problems to anyone. I kept that problem to myself. I learned that what happened to me was bullying and that it’s okay to tell your parents.
