I have a strange hatred for my family and country, Is it okay to feel this way?

OK, It's not that they did anything to me. But my family and country are very old fashioned, poverty stricken, etc etc. So I eventually gained this suffocating feeling that they will weigh me down from having the better things in life. By old fashioned I mean my country and family is used to the beliefs like mental illness = family dishonor, or moving out = abandoning family. I feel suffocated, knowing that these people live by the same beliefs of late 1800's people. Hell, even the "feminists" here believe a wife's job is to keep her husband happy as if her happiness is irrelevant. I feel so disgusted with myself for hating the people that raised me. But at the same time I can't help but feel they're holding me back from having the better things in life. I can't tell anyone about this, I tried telling my little brother once, and he called me retarded and asked what's wrong with me. 

I truly do not know who else to seek support from. Can I have some advice?
