Some of my closest relatives have struggled to pay their medical bills these past few years, so I know just how stressful it can be.
The last thing a sick person and their family need to think about is how they're going to keep their lights on.
That's what makes this story out of Clinton Township, Michigan so heartbreaking. But a hero stepped in just when he was needed most, and we can all take inspiration from his act of kindness.
Christy Stone and her husband Guy had been struggling to pay their bills in 2016.
With job losses and car payments, the couple were working hard to make ends meet and support their five children.
As if that wasn't hard enough, two of Christy's sons had muscular dystrophy, and 18-year-old Troy's case was so severe he needed an electric ventilator to breathe.
The seven machines needed to keep the ventilator running tripled the family's bill.
Because Troy would die without the ventilator, the Stones had even given a doctor's letter explaining his case to the local power company.
But that didn't stop them from turning the couple's power off when they fell behind on their bills - Christy says a missing doctor's signature was the reason the letter was ignored.
When the power was turned off, Christy found herself in a race against the clock to get Troy to a hospital.
The machine's battery had just hours left when firefighters arrived at her home to help Troy.
But one of those firefighters, Ryan McCuen, turned out to be an angel in disguise.
