I’m Anxious and Can’t Stop Overthinking by Nick Trenton is a practical self-help guide for understanding and managing patterns of excessive worry, anxious thinking, and mental rumination. The book explores why the mind becomes trapped in repetitive thought cycles and offers practical techniques to recognise unhelpful thinking patterns, calm the mind, manage stress, and regain focus. Through accessible explanations and actionable exercises, Trenton encourages readers to develop greater self-awareness and healthier responses to uncertainty and everyday challenges. It is a useful resource for readers seeking greater mental clarity, emotional balance, mindfulness, and control over persistent overthinking.
