Since childhood he had battled hypertrophic cardiomyopathy (HCM), a heart condition that posed a constant risk of sudden death.
In his short life, Benjamin -- Ben as he was known to family and friends -- had suffered three heart attacks, including an episode the night before.
Two weeks earlier he suffered heart failure while he was in school.
He collapsed on the campus commons, according to students and the school nurse.
For three minutes, his heart stopped.
Now, after two heart attacks in as many weeks, he and his family were holding church inside their house. The family read from the Bible and prayed for Ben.
"After we were finished, Ben prayed for us. He prayed that we wouldn't be sad or scared," his sister, Ally Breedlove said.
Then, on that day a week before Christmas, the teenager disappeared into his room where he made a two-part video titled "This Is My Life" that he posted to YouTube unbeknownst to his parents.
He used index cards to recount his collapse at the high school.
"I heard them say 'he's not breathing. His heart stopped, and he has no pulse,'" the cards read.
He said he saw a white light.
The teenager said he felt at peace. "I didn't want to leave that place," he said in his video.
Then Ben said he woke up on the floor of the school.
A week later, on Christmas Day, Ben opened presents with his family. They played a game of Monopoly. Then he went outside to watch his younger brother bounce on a trampoline.
"I looked outside my kitchen window, and I took a mental snapshot of Ben smiling," his mother, Deanne Breedlove, said. "That was the last time I saw Ben smile."
Minutes later, he suffered heart failure.
As Ben lay dying, the video he made had gone viral with hundreds of thousands watching it.
It's closing lines: "Do you believe in angels or God? I do."
