Can you try to find a financial advisor through the Cancer Council or Salvation Army or Lifeline or something like that to assist you? At the very least they should be able to help you contact the phone company, electricity company etc and work out a payment plan. That way you can try to pay off $100 a week (or whatever) while staying on top of your mortgage and new bills.
This is one area where our society falls down. Unless you have your own insurance there is no assistance when you become ill and can't work for a lengthy period of time. Even though your spouse or parents can help support you, suddenly losing your income while incurring medical bills is not easy.
Good luck.
