Need advice or a miracle for a desperate family with disabled children.

My name is Veronica I am divorced and in a desperate financial crisis. I don't know where to go fr help. My home is in foreclosure and haven't been able to afford the payments for the past 2 years. I have 4 kids which three have disabilities. My oldest has severe depression and anxiety and bipolar disorders and my daughter has down syndrome which she needs full time attention. This prevents me from working. My 24 year old son works and goes to school and tries to help as much as he can financially but it's hard for all of us. It's been total misery for the past few years. All I'm asking for is advice on how I can keep my home. Some kind of miracle. The bank wants a quarter million just to make a deal and continue making pyments. Where am I going to go with my kids who barely can take care of themselves when we face total foreclosure. Please anybody that can give me advice will be appreciates. Thank you everyone.
