i hate my parents and my life?

i am fifteen years old and a sophomore in high school. I am of indian heritage and my parents are immigrants, but i was born in the U.S. My family is quite wealthy and I have always attended private school and had the luxuries of an upper class family, but the one thing my parents never gave me was love or respect. My parents are always criticizing me and creating a major argument when I make the slightest of mistakes. The other day my dad randomly asked me 'what is fog and how does it work'. I got the majority of the answer correct but i didn't mention that the outside temperature has to be within four degrees of the dew point and my parents stated, "you dont know anything in the world, you are so stupid, how are you going to get anywhere in life". After my freshman year I took the SAT II MATH 2 subject test and scored a 690 without studying because it was a day after my finals. My dad was furious because i didnt get a 800 and revealed his true feelings: "these 690 scores are never going to take you anywhere in life, if you dont get 800 next time I am going to send you to the local public school and stop caring about your future. how does it look on me that I spend 30 grand on my son's education and you get a 690 on the exam. other people will laugh at me saying haha you spent all this money and your son went to the UC System while i spent nothing and my son also went to the UC system". Ever since they received the scores the only thing my dad says to me is 'what did you do today' and 'go study for your test'. If they arent saying that they are criticizing me about how i am a failure because I have a 3.5 GPA in a school where anything higher than a 3.7 in unheard of. My parents always look at the glass half empty they know that I am one of four kids who took honors precalculus as a freshman at a high school ranked top 25 in the country. Lots of times they have said to me that your education is an investment for our future, it makes me feel that they are so selfish and greedy. Whenever i get a bad grade (B or B-) My dad always says "why am i spending money on your future you arent going anywhere, i dont care about your future". Lately I have been so depressed and bothered. I barely talk to my parents right now and they dont say anything to me unless they are ordering me to do math. I dont know if i can take it any longer. I dont know what to do?
