A cancer diagnosis can lead to what feel like impossible questions: How can a person face the fear, sadness, and anger without being paralyzed by them? Is it possible to hold on to hope without being in denial? What is the best way to get needed support? This compassionate book presents dialectical behavior therapy (DBT), a proven psychological intervention that Marsha M. Linehan developed specifically for the impossible situations of life—and which she and Elizabeth Cohn Stuntz now apply to the unique challenges of cancer for the first time. Readers learn powerful skills for making difficult treatment decisions, managing overwhelming emotions, speaking up for their needs, tolerating distress, and living meaningfully, even during the darkest days. Every chapter blends professional expertise, personal stories, and the collective wisdom of other cancer patients and survivors.
