Personally I would not buy a book telling us all how much time and money some people waste on self-help books etc. authored by a wannabe TV celeb from such classics as "Freaky Eaters" and "Wife Swap-The Aftermath" (both to be read in your best throaty cinema trailer voice); who has authored a half dozen popular psychology/self- help tomes himself.

I must confess a personal bias here. I have worked in mental health for over 12 years and only ever met one clinical psychologist who actually helped their patients, as opposed to keeping them occupied with endless rounds of CBT or DBT, reflective diaries etc. until the patient managed to figure most of it out his/her self after a period of years with the help of their families, psychiatrist, peer groups and nursing/auxiliary staff.

A good book (IMO)on the human side of mental health is "Touched by Fire" by Kay Redfield Jamison.
