I support people with mental health and one in particular has BPD at a fairly extreme level and I have been burning out working with. The book is insightful and helpful in assisting me to understand and support clients with BPD.
This is a good explanation of BPD for people who have the disorder and their loved ones. I especially liked the theory of object constancy suggested, it is an interesting contribution. However, compared with other books on the subject I do not feel that it adequately addresses the heterogeneity of the population. It is a "one size fits all" approach, in my opinion. I also truly despite the uncritical way that the authors blame everything - from changing gender roles to social media - for the observed increase in the use of the diagnosis. There are few footnotes - the authors treat these theoretical traditions as though they do not exist - and thereby in my view make some very dangerous claims. BPD is a devastating illness and is cheapened when writers use their own perception of societal ills to explain it away.
