"What if I don't like the education or I can't find a job when I graduate? What happens with my loans? I don't feel as though they are my responsibility."
Well, the Dept of Ed's rules on this are very specific. The Master Promissory Note for your loans, your information that you receive when a loan disbursement is made, on your borrower rights and responsibilities, and in the entrance and exit counseling, it clearly states that you understand that you are still under obligation to repay your loans even if you are unsatisfied with the education you received or if you can't find a job.
These loans are federal student loans, meaning they come from the federal government. If you borrow from the government, then they will want their money back. They aren't concerned with your feelings or your outcome: they just want their money back. Since you filled out the loan, it is you that is responsible for it. Think of getting a Big Mac, eating it, then being unsatisfied with it. Will McDonald's not charge you? No, because then everyone would be unsatisfied with it, and no one would pay anything. That's just one of many examples.
