I feel trapped in my life?

I feel trapped in my life. I have always been the good child, in everything, home, guests house, and I hate it. I play computer about 10-12 hours a day in the past year, about 3-4 times more then before. I think its called my "outlet". Where I can be the bad child, I have real friends. I recently spent a week with my mom. The rest of my family was on a camping trip and now here I was with my mom. She worked until 2 AM or so, came home, slept, got ready, and did the same thing. I did all the animals, including chickens, roosters, dogs, cats, kittens, and my own personal hamster. I took care of them all, including litter box's for the cats and constant food and water refills. My father then comes home, complains about the house, and sits on his lazy butt and watch's T.V. He then eats some pizza then claims were going to clean the house in the morning. He go's out to where my mother works claiming he's simply going to bring a light there and come back, this was at 9:30 PM. He doesn't come back until 2 AM. When he does, I have cleaned a large portion of the house. When I go upstairs to see how he liked it, he simply said "I appreciate it, but you can get up and do some more tomorrow." This was the end of the line. I was a perfect kid my entire life, he would always talk about others complimenting my behavior. Now after 14 years of being "The perfect child" he cant give me one break. He has always complained, along with my mother. I have always been yelled at, and I'm sick of it! I am a human being, and try my hardest. They call me lazy, some call me stupid, but I need my computer even more when they do that. When they yell at me for being at the computer too much, or being lazy because I'm at it too much, I need it even more. Its my outlet, and after typing this I know it is. It's my escape to the life I don't want. I need help, just to last me four years, long term solutions. I need your help, whoever is reading this... Help me.....
