Is She Toxic? Should I drop her?

So I am thinking of dropping this person but I am afraid. My friends that I sit with are friends with her. If I drop her, won't I sit alone? Her name is M*K*Y*A. My experience with her isn't the best. She brags about how she had helped a guy cheat on his girlfriend. She is always in a relationship and that relationship always ends quickly. Yet, she teases my friends and me about how we are single and can't/don't want a boyfriend. She says the n word and her ex boyfriends said the n word. I told her that she shouldn't say it because only black people say it. But she argued with me and said that only non white people can. She always talks about herself and always brings up stuff like," omg did you see how Mrs.P asked if I was ok and if i was crying?" (We were talking about a movie we watched, not even about her) She likes to shove in our faces that she's bi and that she's latino. (She's not bi, she dated a girl once and they never met or even did anything with each other) She constantly puts herself into drama but acts like the victim. I was having a bad day and I didn't talk to her much that day. She went and texted about how I hated her and how I was being bitchy to one of our friends. She makes fun of girls who send nudes but she sent nudes once. She acts like it never happened and makes fun of girls who did. Should I drop her? Should I distance myself? What Should I Even Do?
