Since my sophomore year in high school, I have been targeted by the same girl, no matter where I am at football games, the hallways, at the mall shopping, and now it has escalated to online. She graduated last year, meaning I am a senior. I wanted this year to be amazing: I finally pulled myself out of a dark hole, and I have finally started to accept myself for my flaws. But yesterday, she came back from college with a vengeance. I was at our schools football game and she approached me, yelling derogatory terms at me, ones that should never be used against any female at any age. My friends stood up for me, and I am eternally greatful. But she did it again. Twice in the same night. When she was finally out of sight, I ran to the bathroom and started sobbing. My friends helped me wipe my tears and we went to Waffle House and had a blast. I woke up at 6:00 this morning to multiple messages from my friends, sending me a screenshot of what she posted on her Instagram. It claimed that she did say those things to me, and she was proud of it because it made me cry. She claimed that she told one of my teachers and he agreed with her (that I was a s*** and a crybaby). She did not use my name, but she said that people who want to know who the girl is(me) can dm her for my name and more of the story. I just wanted this to be a good year, and I don't know what to do.
Should I go to administration? Should I involve the teacher that supposedly agree with her? I have witnesses from multiple incidences that can back me up even in court according to my state's anti-bullying laws. My parents want to take this to court, and I just want a non-stressful senior year.
