I think my student loan company is treating me unfairly.?

You have to understand that they have money borrowed which you have received and the interest still has to be paid by them. This means that while you aren't paying them, they still continue to have to pay the cost of borrowing the money themselves so unfortunately I think you will find there is no way to avoid the accrued interest. The penalties for late payment should be possible to negotiate away due to your career path but the institution is likely having difficulties themselves due to the many defaulting borrowers and cannot afford to carry you. They aren't ripping you off, they simply have to cover their costs too
