IM IN A TOXIC RELATIONSHIP HELP

so this girl that I've known for a long time has suddenly started to be extremely rude to me-- she'll constantly say I'm "as pale as a ghost", "dumb", "annoying", "fat", "fake", and the cherry on top "a hoe".   :]    Ex: she had recently fake tanned and she is significantly more orange than me and now keeps comparing herself to me. I was absent from school for a week and now she's always calling me dumb because I'm drowning in late work. I talk a lot and make jokes to try to make people gappy so they won't ever feel sad and she's constantly shitting on me for it (not literally).  I made food for her and ate some of it and said I was hungry and she proceeded to say that my D cups were  there because I was obese. I just won my battle with a hereditary disease that I have (hashimotothyroiditis) that makes me EXTREMELY underweight and I'm finally IN LOVE with my body and she's such a bitch. I love makeup and aesthetic and I put makeup on her and said " I was doing it the way I do it." And she said "OH MY GOD I LOOK SO FAKE EVERYONE WILL THINK IM A HOE".  She constantly tells me I have no butt ( I'm hispanic, so she's fucking wrong) and that I need to cover up my boobs. She always is asking for my clothes and shoes.
