Depression I find to be as fascinating a topic as it is sad. Questions such as: what brings it about; why so few of those who suffer from it, see it; and, particularly, how comes the percentage of people who suffer from it rises year on year, even in places where quality of life is supposedly on the rise. But! This book is not so much about depression itself or the sufferer of it, as it about the caregiver - the partner, friend, colleague etc of the person experiencing depression ("harbouring a black dog"). A good, small, useful picture book summarising nicely advice for caregivers. The advice is split into things the caregiver may notice about the person experiencing depression, things not to say and do, things good to say and do, tips on embracing/acknowledging the black dog together, and, lastly, self-preservation so that the black dog does not rub off on the caregiver.
