Good news, bad news. First good news is you are still hanging in there, congratulations. I know its hard, one day at a time. Next good news, buyers are starting to come out again and the spring market is starting earlier because everyone seems to have held off for so long.
The bad news is housing prices went down for the first time in over 40 years. Things in general are probably getting worst. You need to start looking at alternatives if your house doesn't sell. Do you have to sell? What expenses could you get rid of? How could you perhaps earn more money?
Go to your boss, ask for a raise. Go to your lender, ask them to waive one payment (tack it onto the end of your loan). See what you have that you could sell on Craigslist.
