Just This Once, Don't Call a Friend

Researchers from the University of Missouri at Columbia tracked children and adolescents who shared their hurt feelings with friends, and came to a startling conclusion: The girls who "co-ruminated" the most had more supportive friendships, but also greater levels of anxiety and depression. "Excessive focus on problems probably makes them seem even bigger and harder to resolve," says Amanda Rose, Ph.D., the lead author. "And it likely gets in the way of finding positive, healthy distractions," such as reading a good book or going for a walk.
