What should i do with this friend? 10 points best answer!!!!!?

So i have this friend whom i really don't like that much anymore. Thats because every time i do something that she doesn't agree with she always attacks. For example if i miss lunch she will bombard me with questions . If I don't like pokemon, anime or star trek she calls me shallow minded. She keeps inviting me to hang out with her annoying friends and expects me to like them. In our Chemistry cl she constantly makes fun of me if i don't know the answer since she's like super smart . If I mess up in Chem or anything else not related to Chem she always yells FAIL! What can I do or say to get her to back off?
