Medical & Financial for Rich Mc

This is Rich's second battle with cancer. He is losing this one. Our family has run out of financial resources. Rich only has a couple of months left. We need to cover rent and utilities. When Rich had to stop working, we lost $1500 a month in income. He has applied for Social Security Disability but still has 2 months of the waiting period left. We have too much income for him to get SSI, but not enough to cover ongoing copays for doctor visits and medications. We received one grant that was used to pay some of his medical expenses. At this time there are about $3500 in medical expenses yet to be paid with more on the way. We also need to start planning for his final expenses. We need help to meet all these financial obligations. If we can't find some help we will be evicted.
We are also taking care of our three grandchildren. The middle child has muscular dystrophy and needs to have a home address for feeding supplies and diapers to be delivered to.
We are out of options and can't "rob Peter to pay Paul" anymore.
