Not a medical worker, but my daughters great grandma was diagnosed with cancer last fall, and passed a few days before Christmas. The night before she died her family asked if my daughter could call and talk to her. She couldn’t talk but was conscious enough to hear. My daughter told her she loved her and they said that she mouthed the words I love your too, which was the most she had talked in days. She passed at 5 the next morning. They’re all pretty sure she was waiting to tell my daughter she loved her.
