Save our house

Hi it’s Kathy. My uncle and are in an urgent situation. After paying my uncle medical bills I am severely behind on my mortgage and our house has a severe mold problem from a bad roof. So we are stuck between a rock and a hard place. Either I try to catch up on the mortgage or risk both of our health with the mold. I have pleaded with the mortgage company and told them the problem they will not work with me at all. My concern is my uncles health. I know it’s a large amount of money but I really don’t know what else to do. Anything will be greatly appreciated.
