Originally one of my best friends

There was this girl in my high school school who I’d met just before going there. She was ok until I was like year 9 then she started hanging out with this girl who kept saying the n word to everyone. After a few days she wasn’t her friend anymore. And then she said I liked a boy she liked which was complete bs, she said I said it which I never. A few days later we were friends again. But a few weeks later her and her friend started harassing me over text saying I said things I never said and getting her friend to hate me. And she text me why she said the things, I said I never then she told me to leave her alone so she’s basically not my friend for no reason.
