Why do I hate my parents so much?

Well its not just my parents but parents in general. I think parents are some of the most disgusting hypocrites on the face of earth. Here me out.. when a baby is born parents are all smiles and laughter, happiness fills the room its almost nostalgic and they seem to believe in the fairytale that they will live happily ever after as a family. But flash forward 18 years later its a living hell. In fact most families in America are very dysfunctional and many times it has to do with the attitude of the parents. People like to think its the teen that is acting out but that is not true the parents mid life crisis is far more severe. Its like when you have a puppy that turns into a dog they stop loving it as much and they just want to give it away its the same with children. Everyday is a war zone in my house and they are usually the ones to start it. They want me to leave sooo badly and I personally cant wait to get the fk out as well. The annoying thing is they act like they miss me when I'm away at college which I find so disgusting because once I get home its the same bs all over again. My Father especially I despise him more than anything else in the world. He acts like he owns me and my brother. He has to spend some extra money on me to go to college and he makes me pay for it with verbal abuse especially when I dont get perfect grades. Everything is about money to him I cant wait for him to just die and leave me alone he is 51 this year and he has hypertension so im keeping my fingers crossed. Once I get my own home I will never call that wretched place I lived in for 18 years again. I plan to dissapear and cut them out of my life. Everytime we get into an argument all my mother keeps saying is "afterall we've done for you Ivan this is how you repay us with this attitude" When its not even about that its about how they treat me.. " slightly better than dried up dog sh!t at best" Parents these are your children not stupid financial projects to tout your damn egos around your peers.
