Please help my parents are driving me crazy?

I'm a girl in my mid 20's and i live with my parents. I so desperately want to move out and have wanted to for a couple of years now but i can't afford it. I was made redundant a couple of months ago and everyday i look for work but i'm also at home a lot because i don't have the money to go out really so most weekends i'm at home which i hate. I'm fed up with my parents being nosey, controlling, asking 20 questions about where i'm going, who i'm talking to on the phone, hypocrites, kinda ist only towards their children though. I'm the youngest, i've an older sister and brother. The same thing still happens with my sister. Their controlling nosey etc, she's in her 30's and engaged and has a place of her own!!! my brother is in his 30's and gets away with everything because he's a man and is sssssoooooo lazy around the house he does nothing. I get the talk you know the talk and it's the same crap over and over, i've told them to stop but they don't listen. It's ok for them to lose their temper and my brother but not me. Things have happened in the past and it wasn't my fault but i got the blame and was being kicked out and it was my brother's fault. I'm resenting them more everyday. My sister said i could move in with her but if i do that my parents will be angry with me and they don't have control over me, they won't know what's going on. My sister and i are close and were in the same boat because my parents do the same thing to both of us but not my brother. It really pi**es me off. I've gone past breaking point. I know reading this might sound stupid but if you had to put up with it since you where born and other things you'd understand. Sorry for writing a long text i just me to get it off my chest. Thanks
