My mom thinks I am a Wild Child?

Well I am 10. I'm kn my sisters account but my mom has been yelling at me for being a 'Wild Child' because when she came to my school I started hanging with my friends tryig to do jumping jacks on the ground because we were doing dares. Well then I got pisse off at this one dude and poured coke on his t shirt then she scolded me and took me home. Then she told me that I'm a Wild Child who can only talk. Then I made a chocolate smoothie and she dumped it and said I was fat even though I am the fastest runner in the school. (I'm in 4th grade it goes from pre k to fifth) And she got my brother to call me a slut! And I recently found put wht is is when I looked it up after he called me that! She says that she doesn't love me and I only get good grades because I cheat and I have NEVER cheated in my life. And a guy (let's call him Paul) gave me a love letter, she told me that i am a flirt and I shouldn't talk to boys even though 80% of my friends are boys! I don't know what to do :,( please help!
