For readers who feel exquisitely and painfully hypersensitive, and who blame themselves for it, this book brings validation and a brain-based reason for it: Rejection Sensitive Disorder.

While rejection and failure are challenging for everyone, those with Rejection Sensitive Disorder (RSD) experience them with an intensity that can feel overwhelming, even debilitating. The term dysphoria, which means « difficult to bear, » perfectly describes the emotional pain RSD can cause. It’s not just a matter of feeling hurt—it can lead to physical symptoms such as headaches, muscle tension, and digestive issues, as well as significant mental health impacts like anxiety and depression.

TOO SENSITIVE dives into the neurobiological roots of RSD, helping readers understand how their emotional sensitivity is not just a personality trait, but a deeply ingrained part of their neurobiology. This work offers not only an explanation of the condition but also practical tools for managing emotional sensitivity in everyday life by introducing CALM YOUR MIND, a simple yet powerful system of 12 strategies designed to help readers regulate their emotions in challenging situations. These principles, grounded in diverse therapeutic approaches, are followed by a comprehensive RSD Toolkit that offers in the moment help with dozens of real-life scenarios.

Ultimately, TOO SENSITIVE helps readers understand that emotional sensitivity is not a flaw, but instead a neurological trait that deserves compassion and care. This book provides actionable strategies to transform emotional sensitivity from a source of pain into a powerful tool for personal growth, resilience, and self-compassion.
