The Light in the Middle of the Tunnel is not a self-help book. It's a let-others-help-you book, in which caregivers share their distressing, sometimes overwhelming feelings - and their hard-won self-care skills and wisdom. It's a support group between covers, designed to help readers with the hardest part of the process: dealing with their own emotions. Each chapter takes up one of the emotions that hits a caregiver as the reality of their partner's condition sinks in: anger, fear, sorrow, acceptance, renewal, joy.
