It is exceptionally unfair to not qualify based on parental income being too high, if parents are not contributing. Now get over it.. Hopefully this meant your parents paid for more activities for you in high school thgan your friends...
Review your FAFSA formula...
You do qualify for unsubsidized Stafford loan, right?
You have options, including delaying or slowing down school to age out of the 'dependent' category, or getting married ( if you already intend to marry after school graduation, take a look at the money offset to do it now instead).
Maybe stopping work to focus on full time school completion in your 3rd year, to drive down income and qualify next year, taking out a loan to get by in 3rd yr, then getting a grant in yr 4, paying off loan with it and completing those last few courses while working? You need at least 60% course load to qualify for assistance,.. That should be easy for you to manage work and school.
Does your employer offer tuition assistance? Even ones you have to pay back if you leave before 4 yrs can be treated as an interim loan, assuming you plan to leave...
After reviewing all that, maybe you will decide that you would not choose to change anything after all.
