Teacher student loan pay off

I keep missing the boat! Trying to pay off this dreaded student loan - that allowed me to become a teacher!  Yes, there are student loan cancellations out there --- none of which I qualify for!  I graduated in May of 1998...  One of the cancellations only allows cancellation of loans made after October of 1998!  I missed that boat!   The other teacher cancellation requires you to make 120 consecutive payments - but you had to be employed that whole time.  I, due to teacher cut backs, was laid off for a year which cost me that cancellation.  Again - I missed that boat!  If I could get at least a $1 donation - from 29,000 people...  I could pay off the loan.  I make my payment religiously and I work very hard at my middle school math position.  I spend a lot of my own money to keep my classroom supplied with needs...  If I could get some help with my loan - I could be less stressed and do more for my students...  Thank you for your time and consideration...
