Arline Feilen lost her husband to suicide in 2013. Three years later, she lost her dad to cancer. And this February, she lost her 89-year-old mom to a cascade of health problems. "We were like glue, and that first Mother's Day without her was killer. It just dragged me down," said Feilen, who is 56 and lives in suburban Chicago. "It was just loss after loss after loss, and I just crumbled."
