I was diagnosed with post-viral CFS in 1988. This book is an excellent description of living with CFS except for one thing: 3/4 of marriages affected by chronic illness break up, which means that most of us don't have the live-in support system she had.
Some disbelieving doctors like to attribute CFS to "secondary gain" or enablers who allow the patient to "enjoy the sick role". Unfortunately, for many CFS patients, there's no enabler and the only thing you gain is the stress of trying to make ends meet with no income.
Wall tells of having someone run her bath, gently wash her, dress her, and help her back to bed. That's a luxury most of us don't enjoy. If I'm not well enough to cook, I don't get dinner; if I cannot safely get in and out of the tub by myself, I don't bathe (on a cold winter day when I needed a bath to warm up, I got stuck in the tub for over an hour because I lacked the strength to boost myself up and out, and there was no one to call for help).
Wall's live-in support structure allowed her to do what those of us who live alone can't: use all her energy to write a book to explain to the rest of the world what it's like to be trapped in a body and brain that don't function.
I recommend this not only to patients, but to their friends and family as one of the best patient-written books I've read.
