Help with revision :(

This isn't a question about GCSE topics, but I really need help. Basically, long story short, I have the worst relationship ever with my sister (basically no relationship) and she's home from uni this Easter. All she does is argue and scream and swear at me and my family (all the time) and this is the worst time because I really want to study and get great grades it's so tiring listening to her insulting everyone all the time and I just can't focus anymore! Help please
