Great idea to share...
The book that helped me the most and I continue to reference is "How to Be Sick" by Toni Bernhard
http://www.tonibernhard.com/SummaryHTBS.html
It's written for chronically ill and their caregivers.
I also purchased "When things Fall Apart" by Pema Chodron but haven't started it. It was referred by a friend also suffering from CRPS.
