When Living Hurts
This book is geared to teens facing depression. Because of the age, I would weed this without a second thought. Treatment of depression and other adolescent mental health issues are better understood today. In any material geared to teens and their parents, it is important that this material be as current as possible. Cultural references and technology can age a book very quickly, making it effectively inaccessible to those who need it.
Depression and other mental health problems are not something someone can just suck it up and fix with vitamins, exercise, or positive affirmations. Teens mental health problems are often dismissed as being a normal, moody teen, especially years ago. Be brutal when weeding teen items, especially as they pertain to health matters.
