The book is a lot better than the film - the book actually deals with the emotions as feelings, rather than a plot or comedic device. Although I thankfully haven't needed help it did help me to understand the processes involved and some of the jargon without having to ask insensitive questions.

I cried at the book but not the film, but the book also made me laugh a lot more than the film - which scored laughs mostly because I knew the bit in the book.
