A book that changed my life

While dusting the copious books shelves we have in our house, I came across a book that really did help me through a pretty difficult time in my life. My mother has had multiple sclerosis for many years and while it's a difficult enough ailment for the sufferer to cope with, because of it's nature (few outward physical signs to start with, the ability to put symptoms down to stress, or strain etc.) it's often hard for the family and friends of the sufferer to understand what's going on. This book helped at a time when neither my mother nor the doctors could really put the why's, how's and what if's into words. I'd recommend it for anyone else in a similar situation.
