I'm confused about this friendship

When it is just the two of us, she compliments me , but whenever we're around other people, she acts differently. She's laughed at my face, chest size, height, weight, and even my dreams. I told her I wanted to be an esthetician and she laughed, and basically told me I wasn't qualified. She took other friends to see a movie I wanted to see and excluded me from the outing. She even joined in on a racist joke about black people and laughed in my face. Too many things to name, yet she always gets me birthday and Christmas gifts. Y'all idk.
