Help me? I don't know how much more I can stand?

I hate my life. Sometimes I think it would be easier for others if I hadn’t been born. I’m 14, I have two younger brothers who are 12 and 8 years old. My brothers are very immature. They constantly talk about es and eating our cats. The 8 year old was like, “We’ll have blahblahblah for the maincourse, and blahblah for the side, and blahblahblah for the appetizer..” and It’s disgusting. I know theyre not being serious, but it just repulsive me that they can just talk like that about other living things. Most of the times my parents ignore them, including this time ._. . They don’t disapline them AT ALL, especially the youngest. My brothers get in fights all of the time with each other. It used to be the 8 year old’s fault, but now the 12 year old is being a BAD ROLE MODEL for this younger brother. I don’t know how much more I can take of this. my parents have tried everything with the 8 year old… , time outs… but I guess they just gave up. So today, me and my brothers were picking out a Christmas movie, and we couldn’t agree on it. My brothers kept on arguing over how I moved a lot in my sleep, as I usually sleep on the couch with my youngest brother. They kept on blaming it on me like It was my fault. how is it my fault if im a sleep?? im not controlling what im doing when im sleeping. then they just started fighting and throwing things at each other. The youngest stuck a football between his legs, and pretended it was his p****. My parents did NOTHING to stop them, even after I told them what they were doing, and I had a cat sitting on me so I didn’t wanna get up. I said, “If you don’t turn on the movie, im going to start talking about . I asked my brothers, “do you know what **** is? **** is?” to get a reaction out of my parents who were in the other room, and in the hopes that my brothers would turn on the movie . My mom comes in the room, yelling at me, blaming me like It’s 100% COMPLETELY my fault. She didn’t lecture my brothers as much as she did to me, and she didn’t even start “lecturing” them until after she sent me up to my room… she still let my brothers watch a movie, but not me. This wasn’t fair, so I unplugged all the plugs from the tv. I hate my life. I hate my brothers. I really didn’t know how much longer I can deal with this. Its been like this for YEARS, and nothing’s ever changing, its just getting worse. its just getting so tiring and so stressful. I feel like my parents don’t displicine my 8 year old brother enough, and my brothers always fight. I feel like I always get blamed for stuff. and I have no idea what to do anymore because I cant take it anymore.
