If there is something you really want, don't get sucked in to that "quality of life" thing, because people mistakenly take it to mean having a life full of material goods, including a good car while working at a job you hate.
What really brings you quality of life is doing what you love to do, and if that means not going to college then that is the route you should take.
But it is entirely beside the point: It sounds like your parents are scared about your future and don't want a "failure to launch" scenario, understandable but annoying given your situation, so you might want to talk to them about what you are going to do when you are not going to college (when they seem apprehensive, and they will, just tell them that if it doesn't work out you can always go to college "later").
