Kiddo (and I'm not being condescending, I'm old enough to be your mom...'s best friend) there are just so many red flags in your statements above, if i listed them all I'd basically be rewriting your whole statement.
You are just starting out in life. Just starting a job, just starting college, just turned legal age for stuff...why don't you slow it down a bit and get yourself in order. It's not a question of "being fair" to you. Nowhere does it say a parent's job is unequivocal fairness. Their house, their rules. Period. They don't have to be fair.
I think you show great wisdom by heeding Avsha's advice on including your parents in the decision, because ultimately they have the right to make the call one way or the other. You would show great foolishness to blow them off and do what you want to do.
There is no downside to patience. But many when you act impulsively.
