They call me a whore, and I dont know why.

I’m only 14, and I’m brand new to the local public high school. I just came from a Catiolic school. Its the 4th week and I have already herd people calling me a whore, I have no clue why. But it kills me. I’ve never had sex, I dont flirt with guys, and I’ve only kissed one guy. I got called a cum dumpster in front of the whole class. They all laughed. My brother has gone to that school for 3 years and tells me how I’m a whore. So I can’t even get away from the names at home. I’m also abused my my mother. It was physically till this January when I had to call the cops on her. Now its verbally. I get called a whore by her, a *****, and she asks how she gave birth to such a demon. I’m also a dancer. I dance every day but Sunday. Its a competitive dance team. There is so much stress. Especially because I know I’m one of the worst on the team. I have dyslexia so it makes dance so hard! Every where I go I feel out of place stupid Help.
