Desperate for change

I really need to get out of this situation, the situation being my family and I.. I would rather go to boarding school then have to live here, there is no life here for me, although it would be extremely hard to leave my friends i cannot even imagine that, most my time is spent at home anyways. Although alot of people would say they are the best parents you could have!!!!!!!!! I do not see that, and no one is me so you do not know how they change towards me. I JUST WANT A NORMAL LIFE WITH A FAMILY THAT DOES NOT CARE AND TREATS EVERYONE THE SAME.My Job will be gone in a few days thanks to them, then how am i supposed to earn money. My parents keep telling me that year 11 and 12 are the most important of your life which i know is true, and dont worry you don't need money. But i have news for them , i want to move out and I need money for that so why can't they just leave me fucking alone and get on with there lives. The reason why I am soo pissed off is because my immature, goody tooshoes brother, who rats on me and everything i do/ am going to do, who gets a fucking (birthday present)8 months after his birthday all this shit they make up comes into this room and stares at the computer screen to annoy me all the time.He has came in atleast 15 times in the past minute. If I don't get my laptop back which i paid thousands of dollars for and has been sitting at dad's work for over a year cause he can't be fucked, I am going to loose it.
