I feel caged and i desperately want and need to be free?

im 19 years old female college student and my problem is that i live with my mom and she is very possessive and controlling and strict... i want to live life freely without worrying about getting home 30 past curfew that she has set for me.. i would pack up and leave right now but then i would have to drop out of college because i'm dependent on her (i use her tax returns to receive financial aid without which i won't be able to pay for college) and everybody tells me that there's nothing i can do about it unless i marry or get 21 years old... i want to be independent, hang out at night jazz clubs from time to time, travel.. i can't do any of those things right now because of my mom. i am this young and energetic once and i want to experience stuff.. i don't care about material things, i don't mind living in a studio with roommates and can live on conserved food, but i do care for the education and basically it is the one thing that keeps me caged with my mom.. what should i do? i know 2 years aren't that long but im very restless, i've already wasted much of my life and i don't want to be wasting any more time..
