Wow, there are some pretty nasty posts in this thread.
The OP asked our advice so why do we all assume that it's a wind-up or a joke?
I wouldn't wish this situation on anyone. The OP has suffered abuse which is actually a problem in the UK.
To the OP:
Please call Childline. You say you are a subject of domestic abuse. They will be able to help you.
Call Samaritans when you turn 18.
Ask your friends to help you and contact any relatives with whom you get along if you can. From your situation I imagine that this all stops very soon. Indeed, you probably wont be able to access a computer with internet soon.
If your father is abusive then dont go home. Call the charities who deal with cases like yours and far worse regularly.
Call the Citizens Advice Bureau and contact the Army to speed up your enlistment.
If, however you acted in the wrong and things are not truly desperate, please go home and apologise for whatever it is you did.
I really hope things look up for you, and good luck.
