Billy's mom, Barbara, says his weight started increasing in elementary school. "In kindergarten, he was a little chunky, and I used to tell everybody, 'Oh yeah, he's going to be my football player,'" she says.
As a teenager, Billy's weight began to affect his life at school. Barbara says he had trouble getting up and down the stairs, and his fellow students weren't always kind. "He did graduate, but he did it here at the house," Barbara says. "He just got to the point where his whole life stopped."
