An Upstate girl with a rare form of cancer is helping make Christmas special for another boy and his family.Riley Faith, 5, was diagnosed with stage 4 adrenal cortical carcinoma in 2020. She's been in and out of the hospital, undergoing immunotherapy and traveling back and forth to New York for treatment.“Riley likes to give things to other kids who have bad spots," Riley's grandmother Tiffany Page said. "That’s what she calls cancer.”Page said Riley started "Riley's Cozy Comfy Mission" this year.“Riley cares about people and she wants to make a difference," Page said.As the holiday season began, Page said Riley started collecting Christmas gifts for other families with children with cancer. “And then she found out about Carter, and she wanted to do more and buy more gifts for his family," Page said.When they learned of Carter Hord, 12, who was diagnosed with a brain tumor, Page said Riley wanted to collect gifts for his family too.“Sometimes, it’s actually better for the giver than the person receiving,” Page said.On Wednesday, Riley and her family surprised Carter, his brother and three cousins with some Christmas gifts.“It was a moment that I haven’t gotten to have in a long time,” Carter said.Carter's mother said it's been a long year for their entire family. She says she remembers the few hours leading up to the moments their lives started to change.“We were sitting there watching TV and he just said, ‘Mom, I don’t feel good. I don’t feel right.’ That was Dec. 6," Carter's mother Jamie Crisp said.On Dec. 7, Crisp says Carter was diagnosed with a brain tumor called DIPG.She says it was bittersweet watching her children and their cousins open gifts Wednesday. “It’s so much joy and I’m watching all of them,” Crisp said.However, she says the tumor has impacted Carter in so many ways over this past year physically and emotionally.“But seeing that is hard," Crisp said. "Watching that is hard because this tumor changed his personality.”Through all the joy and fun during the holidays, she says there are still worries that linger in the back of her mind.“What I want I can’t have," Crisp said. "Not without a miracle.”Carter says he and his mother have been strong for each other, lifting one another up when the other is down.“It can also get emotional," Carter said. "Sad, happy.”Crisp was able to watch her son just be a kid for a few moments today, sharing some emotional words with him. “I am so proud of you, for everything," Crisp said. "You’ve been so strong.” Despite the unknowns that lie ahead on both Carter's and Riley's journeys, their families came together in a simple act of kindness, sharing hope with one another.“It’s just hope because hope never goes away," Crisp said. "I will have hope until I can’t anymore.”
