You can only take out 5.5K Freshman year, 6.5K Sophomore and Junior, and 7.5K senior year. Any other loans would have to be cosigned by your parents.
If they are willing and able to pay, let them, and work hard to make good on their investment. Perhaps a little distance will enable you to come to a better working relationship as you transition to adulthood. And if that doesn’t happen, perhaps you can develop strategies so you can repel any future attempts to guilt trip you.
