The Big Sad is heartfelt story about Bentley Bunny's growing struggle with anxiety and childhood depression, which he refers to as "the Big Sad." It addresses the very real emotional and social impacts of anxiety and depression and offers reassurance through the lessons taught by those closest to Bentley. This book is based on my son, who has had a real journey with the Big Sad, and the impact it has on his daily life. As a mother, this is my gift to other mums living with stressed-out, anxious bunnies.
