Help for family with terminal cancer diagnosis

Ok'd by mom for update: new dx of stage 4B cervical cancer. Extended medical bills, not being covered, daily living expenses, gas for trips to the many appts coming up. Dad will not be working much as he is primary care giver. I am helping as much as I can as well. My parents have fallen on hard times. From extensive house repairs to health concerns turned to more serious matters. Mom has been diagnosed with uterine cancer along with other health issues. Dad still continues to work, but will be needing time off for upcoming medical appointments for Mom. While some of this will be covered, daily expenses like food, gas, and other things will not.
