This will be hard but it can be done:
I don't know if you live near your parents - but I would move back home and live with them for the next 1-3 years if they are ok with it. This is no time for pride - you don't want interest to collect on that which would take you years. Live back home if possible and put every cent of your paycheck towards paying off the loan. No vacations, no shopping, no eating out, no expensive holiday gifts, etc. etc. If you have a cellphone - I would even get rid of that and just use the home phone.
Tighten your belt for 1-3 years and you can be debt free forever (if you continue to spend within you means).
Here is a system I found really helpful:
Here are some tools you could start with incl. budgeting
I know some people might find it too extreme but that is what I am doing. I want to enjoy the rest of my working years without worrying about debt or incurring crazy interest. Furthermore I am single so if you are married/have kids I know this is not realistic.
P.S. That does not mean that you have no life - trust me there are hundreds of fun things you can do for free - picnics, biking, visiting library, going to the beach, visiting the free landmarks/attractions of the place you live, playing board games, inviting friends over for a movie on the tv, having potluck etc.
