Garnished wages/Convicted felon

I took student loans while in college. While in college I was convicted on a non drug felony charge. I was still able to take loans. I went to schoold for education. However upon graduating i was unable to get a job in education because of the felony record. I struggle for years to find gainful employment...years later, after finally getting a job and attempting to make good on student loan debt and other debts, I was unable to make payments and eventually had my check garnished. I am not disputing the fact that I owe money nor am I disputing the garnishment itself. I am however in despair over the fact that the original 50,000 debt is now 100,000 thousand with interest still accruing. Is there a way to negotiate that some of the interest be forgiven? I have read some things indicating loan forgiveness due if you went through a course of study that wouldn't benefit you but you were given loans. Again, not looking for a free ride just a more manageable one.
