Wife died from cancer

My wife passed away a little while ago after losing her battle with cancer. I am now on a fairly frequent basis getting bills regarding out of pocket treatment and testing expenses. My insurance paid some but at the rate I am getting the bills I will very shortly owe at least 7000 dollars as I keep getting bills from more hospitals and physicians I will shortly owe at least 11,000 dollars.
I would greatly appreciate any assistance financially. I am not able to pay a penny for those expenses right now because while I do have a job at a great company I am going paycheck to paycheck and have no extra money for payments or savings.
