A place to live

Hi my name is Amy..In three weeks the house that my sister and I live in will be sold at auction. I'm 55 and my sister is 63 and we are both disabled. We take of my sister's four year old grand daughter while her mother works. We have to be out the day of auction. We are on lists for an apartment but have no where to go and no money to rent something even temporarily. Any donations would be appreciated
