Based on an 8-week Mindfulness-Based Cognitive Therapy program, this guide addresses the growing need for tailored mindfulness in managing ME/CFS, fibromyalgia, Long Covid, and other chronic fatigue conditions. Using contemporary understanding and theoretical approaches to Long Covid and ME/CFS, this book enables practitioners to understand how they can adapt their teaching to meet the specific needs and challenges of patients, including adjustments for brain "fog," approaches to rest, movement, daily activities, and difficult thoughts and emotions. Contributions from individuals managing ME, fibromyalgia, and chronic fatigue through mindfulness are included alongside practical guidance and detailed week-by-week session plans, whether for in-person or online sessions. Enriched with helpful diagrams and illustrations, professionals can use this guide to significantly expand the range of individuals they can reach and gently empower clients living with often isolating conditions, showing them how to apply this approach long-term in their daily lives.
