Saving my moms house

My mother has had the rug pulled out from under her with her house. She was served papers friday from the morgage company that she has to pay three payments of the above amount listed. This has my mom at a loss. She doesnt have the money for the first payment due november 23 let alone the next two. she was not given any heads up before last friday. Shes under a lot of stress and its hard to see her struggle over this. Its hard to reach out for financial help so I thought I'd do it for her. My mom is a hard worker and anyone whos knows her knows shes been working her butt off for a long time.  Anything helps!
