In Thinking in Circles: The Psychology of Obsession and Compulsion, this groundbreaking book sheds light on the complex interplay between intrusive thoughts, compulsive rituals, and the emotional turmoil that traps so many in cycles of anxiety and fear. Drawing on the latest neuroscience research, the book explores how brain circuitry and neurotransmitters like serotonin contribute to the development of OCD, illuminating why certain repetitive behaviors and thought patterns become so difficult to break. Readers will gain a clear understanding of the core symptoms of OCD - from checking behaviors and mental compulsions to the relentless battle against intrusive memories and fears of contamination or harm. More than just a clinical guide, Thinking in Circles delves deeply into the lived experience of OCD sufferers, capturing the emotional distress, shame, and isolation that often accompany the disorder. It emphasizes the importance of emotional regulation skills, psychological resilience, and the transformative power of mindfulness meditation and exposure therapy. The book also highlights evidence-based treatments, such as Cognitive Behavioral Therapy (CBT) and Exposure and Response Prevention (ERP), alongside emerging integrative approaches. With practical insights into managing anxiety and cognitive distortions, it offers hope for recovery and relapse prevention. Designed for individuals struggling with OCD, their families, and mental health professionals, Thinking in Circles is an essential resource for understanding and overcoming compulsive behaviors. It challenges stigma, promotes mental health awareness, and guides readers on a compassionate journey toward self-acceptance, healing, and freedom.
