Let Your Light Shine Through ManualÂ
Â
A Practical Roadmap for Living Better with Complex Chronic Illness
If you live with ME/CFS, fibromyalgia, environmental sensitivities, long COVID, or related chronic conditions, you have probably experiencedÂ
- confusing and conflicting medical advice,
- strategies that work for others but not for your body,
- exhaustion from trying to figure everything out alone.
Let Your Light Shine Through was written to change that.
This manual provides a clear, science-based roadmap to help you understand your symptoms and apply practical strategies that support stability, function, and quality of life.
Written by Dr. Eleanor Stein, a physician who has worked with people with complex chronic illness for over 35 years—and who has lived with these conditions herself—this manual distills decades of clinical experience and research into tools you can apply in everyday life.

What Readers Are Experiencing
"There is hope and this book offers a guided pathway - I found this book inspiring and even more enlightening than the first edition. A must read for anyone living with these diseases." - Ann
"Highly informative, thorough, and easy to read - Dr Stein has written a comprehensive guide for the management of ME/CFS/ FM which comes from almost three decades of experience as a patient as well as a physician. This book is well organized, easy to read and full of practical advice and tools for both patients and providers. It is based on science and well referenced. It includes approaches to management of co-morbidities associated with these chronic conditions, many of which are outside of the scope of physicians and providers who do not routinely treat these complex patients. As a patient myself, I recommend it highly." Joan
"A practical, compassionate guide you can actually use - a comprehensive yet accessible guide for anyone managing chronic illness. Dr. Stein’s extensive clinical experience shows on every page. The fictional character Joan runs throughout, making the concepts relatable and easy to picture in your own life. Each section includes practical tools like charts and tracking logs to help you gain real insights into your own health. The book is designed to be worked through sequentially, though she encourages you to start with whatever is most pressing, for me, that was sleep." - Ruby
"This thoughtful, grounded manual offers a flexible, nervous-system-informed framework that emphasizes self-observation over rigid rules. Compassionate, practical, and deeply credible, it’s a steady guide for anyone seeking understanding, regulation, and forward movement without fear." - Raelan Agle, MSW, Author and YouTuber
