According to the article, the father got laid off, medical coverage was lost when he was laid off. The medical bills were not stopped due to the condition of the kid. They refi'd the house to make ends meet and the mortgage payment went up. The medical bills are still coming in and are not covered by their insurance. Taxes on the property went up because the value of the property was raised by the new larger and expensive house. Pretty simple to figure out there. These folks problems are not the fault of the show, it's the job situation and mortgage situation.
