Hi Ed, first of all has anyone told you about the free consultation this site offers? if not that would be the first move I would make to see what a debt professional says, they will offer you options that you have tailored to your situation.
Secondly, the good thing is you're current and hopefully you can stay that way, as frustrating as it is seemingly going nowhere, keep in mind that keeping current is very important.
Have you contacted your creditors to see if you can get that interest down some and get the payment a little lower so more $$ goes to your principal? if not, please do that.
I think that the consultation will offer you lots of help. others will be along to to give you more ideas. good luck!
