My dad is suffocating my life?

My parents are both korean and live out family life according to traditional korean customs. Basically they treat my life as their own. Yes I know and appreciate that they love me and want the best for me but sometimes I just can't stand their intrusion into my life...sometimes I feel that to them Im not an individual but a dumb little child that has to be reminded about the most inconspicious aspects of life. Whenever I tell them (especially my dad) that I am old enough to make my own decisions they/he rudely disregards my words as if spoken from the mouth of child. Also he has never told me to my face that he loves me and as a child I was never complimented on anything and critisized for everything that didn't meet their standards. When i got poor marks (which were better than average) in elementry school I got whipped with a stick. when i was still young i held a kitchen knife while crying thinking of killing myself. My dad loves me excessively but is too proud to show it. HELP!
