Help please

We are a senior citizen couple. We are homeless now. My husband is in endstage renal failure. No function in kidneys. He is hypertensive. His health is very frail. He was on life support not long ago. 6 months in hospital. We can only afford at max 450. If all bills are paid. We both have worked every day of our lives. We are honest people with no criminal record. Who would think you would be a senior citizen thats helped, taken in others, helped the homeless brought them into our home..and at 66 years of age..we are on the streets.
