Please help us keep our house

2 years ago my wife was diagnosed with breast cancer and had and still needs surgeries.  To date we have spent over 18k out of pocket.  Then I got injured and lost my job and insurance.  I had major surgery to replace my right femor, that was 10k out of pocket that I don't have.  Now we owe 3k in taxes on our home and in Mississippi if you cannot afford your taxes anyone who pays the taxes due gets the house.  We have sold ALL our assets to pay the medical bills and now has depleted all options for additional money.  Please I am begging, my house is mortgage free, and to lose it for 3k dollars will literaly put my wife and daughter on the street.  In 30 days we will lose our hom!!!!  Please help.
