Emancipation

I've not been getting along with my parents (mostly my dad) and we always have a fight and I'm so sick of it. I want to leave my parents. Currently I live away from my parents for studies and obviously they r paying for it coz I don't earn any money. I'm 17 and turning 18 this June. I have a full plan of what I'm gonna do in next few years and build my career on but my parents want me to go this other way as they have spent a lot of money over the years on that ..but I wanna take up something else as a career option ..can I legally get rid of my parents? (as in emancipation)....and I don't have a job currently and I don't earn anything so how can I get help on that? can I get a loan, like education loan?
