I finally found this book at the bookstore today and bought it!
Actually, I read it about 17 years ago and threw it away. But i keep remembering this many times and tried to buy it again but failed ( even in Amazon!).
It is about the authors experience of being depressed. The trigger words were “Are you teaching quality?”. He kept thinking what “quality” means, and then his body and mind went out of control.
What a sad story!
I think anyone who had suffered depression will sympathize with author…..
