What is there to address? What you've said is that you can't survive without someone else paying for you. Nothing wrong with that, as many teenagers, even those 18+, are certainly in the same boat and hope their parental units will continue to provide a tremendous amount of support. Including picking up a chunk of that $23K/year you list as college expenses.
What you don't seem to be grasping, is that you have no inalienable right to force her to pay for you to do just about anything at this point. Either you can be self-sufficient, or you can't. Binary. If you can't be self-sufficient, then you pretty much have to agree to her conditions for that financial support. Either explicitly or implicitly. Trying to game the system just isn't going to work. You don't have a right to a bike. You don't have a right to college. You don't have a right to much more than life, liberty, and the pursuit of happiness like the rest of us. I think you're going to look back at this thread in a few years and feel a bit differently than you seem to be expressing so far.
