Two 12-year-olds formed a powerful bond while they were both being treated for cancer.
Stella Usiak and Lucas Lowe met when they began treatment for Acute Lymphoblastic Leukemia at the Roswell Park Cancer Institute in Buffalo, New York.
Since then, a lot has happened. There have been ups and downs. They both underwent bone marrow transplants and much of their time is spent at the hospital.
But in the midst of everything, their friendship strengthened, and blossomed into love. They go on "dates," consisting of lunch, followed by a walk and some conversation. Lucas pushes Stella in her wheelchair.
"He worries about how I'm feeling just like I worry about how he feels," Stella told WFAA.
They lift each other's spirits when things get extra tough. Last month, Lucas made a video for Stella where he held signs cheering her on and proclaiming his devotion.
"It made her feel special and she cried and I cried," Lucas said about Stella's reaction to the video.
"It was amazing. I've never felt that way in my life, ever," Stella said. "It made me so happy. It made me feel like I'm a princess."
A hospital nurse said their relationship is so important because only they know what it's like to be in their situation.
"No one really knows what a kid with cancer is going through -- not the parent, not the nurse, not a friend -- the only other person that knows what a kid with cancer is going through is another kid with cancer," said Nurse Angelica Zachara said.
