Probably you dont feel like talking to your mum to find out if there's anything she's going through atm. Im afraid my best friend is going through same thing with her dad, but her mum is there (though she does nothing). My friend is doing all her revision in public library - until it closes at 7pm at least, then she goes to Borders and places like that to work. Spends as little time at home as possible and relies on her friends support, tries to avoid her dad and the arguments. She is moving into a flat as soon as possible - she has a job atm so saving up, then she'll work full time at Pizza Hut till uni. Depends if your that desperate to move out, or if there are any other relatives or friends you could move in with.
