Cremation and Tax Help

My mother died. She left no will. We can not afford her cremation and the house we have lived in for 19 years is being lost. I took care of my father for over a decade when his back pain became unbearable and for 6 months as he rotted from cancer. Then I took care of my mother for years as she did not drive. We paid the ALL the bills here for years. My 11yo son is losing the only home he has ever know. We cant afford her cremation, the back taxes, and the inheritance tax. I am at my emotional end. Even though we hide it from him he realizes we are losing the house. I am worth 250,000 dead but alive I am worthless. Please help my wife and son.
