Depression is a common and debilitating problem among women, though it rarely occurs in a vaccum. As Susan Nolen-Hoeksema's original research shows, overthinking--a tendency to ruminate on problems rather than to seek solutions--often co-exists with unhealthy eating habits and/or heavy drinking. In fact, 80 percent of women who report suffering from one of those also suffer from another. This groundbreaking book, written in a vivid narrative style that captures the complexities of women's lives today, explains how the three core problems of the Toxic Triangle reinforce one another, wreaking havoc on women's emotional well-being, physical health, relationships, and careers.
