"Our whole world just flipped upside down," said Still in a video posted on a site for Leah. "I don't want to lose my daughter. And it scares me to death that she has a chance of not being here. She's my best friend, I love that girl to death. I don't know how I would be able to hold myself together if something ever happened to her."
But right before Thanksgiving, Still took to Instagram to announce some great news: Leah's cancer is in remission.
And through it all, Leah managed to keep her positive attitude. It's an amazing story of resilience, and we wanted to send our absolute best wishes to the Still family.
