A toxic friend of mine is moving away

One of my friends, probably the worst one I ever had is moving away. She hated me and spread rumors about me but I'm still not quite sure why she hated me so much. As far as I know she hated my entire family. I lied to her once about watching season eight of my little pony because she was obsessing over it and I wanted her to shut up instead of try to tease me with spoilers. Unfortunately I'm terrible at lying and she saw right through me, but that was months ago so I don't think she'd be too upset about that. She also labeled me as "White" all of the time even though I'm only half white like her. Not sure if she had strong feelings about that but I don't have anything else that i remember she really expressed her hate of. Maybe it was the fact I liked dark chocolate and she liked milk chocolate? Did you ever have a toxic friend, if so how did you deal with them??
