I have family. These people take care of me. They take care of me every day of my life, and without them I don’t know what I would do.”She tearfully heaped praise on her 11-year-old daughter, Sadie.“The most important person in this world is my daughter,” she said. “You are so much more, you are so much more than even you know. You are so beautiful and kind and loving and smart and interesting, and I am blessed every day that I get to wake up and take you to your school. … You are my everything. Thank you for standing beside me through all of this.”US actress Christina Applegate looks at her newly unveiled Hollywood...
