Day said on an Instagram post that she died peacefully Wednesday night. Day’s sisters and one of their children were able to leave Australia for Columbus to be with her as her condition worsened. “We are heartbroken but incredibly grateful for the gift we had in her living with us for the last almost two years full time,” Day said. “She fought so hard until the very last breath. I am forever indebted to her for the sacrifices she made for me to be successful, and for the person she helped me to become. We will miss her so much.”His father died from stomach cancer when Day was 12.
