I HATE MY DAD SO MUCH?

I ABSOLOUTLEY HATE MY DAD >:@ he's just sat us all down to say that for every day my room isn't tidy he will subtract money from my pocket money. 1 pound for first day, 2 pounds for second day. IM GONNA HAVE NO POCKET MONEY! and i am a twin so I share a room, and I asked him if i could have my own room, my mum agrees with me, but he said no we have no money, and then went and bought a tv and a PS3! all my friends will laugh at me because they get laptops and ipods for their birthdays, and im lucky to get fifty pounds! he's put a timer on the laptop, and a password on MY name, because apparently im spending too much time on the laptop, but all he does when he comes home is go on the laptop till midnight. HES RUINING MY LIFE! he said he will continue doing the money off my pocket money untill i am 18, and that if i carry on being 'rude' (I told him his pocket money thing was stupid) he would come and take money off me when i leave home! he said that when my measly ten pound a month pocket money runs out he will take it off my birthday money, and he's doing it to my sister, but not with the birthday money! I'm 15! when will he stop treating me like a 6 year old ! How can i convince him to stop being so stupid and let me grow up ?
