Nikki is a high school teacher in Corning, New York, who learned that her mother may be dying of cancer. Nikki says she has become angry with God and questions his choices. "If there's a God, why would he give such a wonderful person this kind of disease? And why would he put my little siblings—I have a 9-year-old sister, a 12-year-old brother and a 21-year-old brother in college," Nikki says. "Why would God want to put these two little kids through something like this at such a young age?"
