It has been a couple of months since I finished this book, so my memory is getting rusty, but my general impression was that it is full of a lot of good resources but poorly organized. On the positive side, the author has generated an incredible resource with his online forum connected to the Stop Walking On Eggshells books. But:
My overriding criticism is more about this field of psychology than the book in itself: To me there are two very distinct categories of BPD - high-functioning and low-functioning - and because they manifest so differently and present totally different treatment needs it can, at times, seem like a waste of time as a family member to read about coping skills for dealing with the wrong category of borderline personality.
As the family member of a high-functioning borderline personality (let's call it HF BPD), I am not faced with the challenges of life-threatening addictions, reckless work or spending habits, or self-harm behavior that present in the case of low functioning BPDs. At the same time, I face a constant struggle with a personality that is self-convinced that, for a well functioning employee and active citizen, therapy is not needed - as a result, the underlying terrifying fear of criticism kicks in to wholly reject any suggestion of therapy, which is seen as a form of attack. This dynamic is the single most challenging aspect of having a loved one with HF BPD - not only does it make it very difficult to make any progress toward a more peaceful life for the borderline himself or herself, but it is also extremely isolating for the family member, who faces the constant trauma of being accused of being the source of endless conflict but who lacks any ability to deal with the problem professionally, except in a sort of ALANON context of therapy (as in, my loved one is an alcoholic - or BPD - and I deserve treatment to cope with it.) Even in the process of seeking therapy as the family member of a HF BPD, months or more are spent getting past the preliminary question of evaluation and reassurance that it is the HF BPD who is the genesis of most conflicts, before the family member can actually begin to dig through the experiences of responsibility, guilt, and healing that need to be addressed. A ready resource for family members and their own struggles is sorely needed.
The author clearly understands the drastic difference between this type of personality and a lower functioning and unstable BPD, but does not economize the book to make it more useful for each category of family members to find the right resources. I'm not a professional, but I would assume that the advice for each category of family members would be drastically different: in one case, for the safety of the BPD and those around him or her, it would seem imperative to urge therapy - and that effort would more likely to succeed given the personality's propensity to hit rock-bottom. In the case of a family member of an HF BPD, I think the priority might often be to discourage therapy for the personality, which could be more destructive in the end due to the HF BPD's deftness in skirting self-analysis; and instead it's more advisable to work individually with the family member on coping and interacting skills and rebuilding personal stability and peace. In the end, I guess what I'm saying is that there should be two different books.
And to bring it full circle with a post-script, this problem really stems back to the central problem that this disorder is mis-named. While I can't speak for low-functioning individuals, so forgive me if this is flippant of me to say, it seems that it matters less what your disorder is called when you're fighting for the will to live and finding yourself on a yo-yo between sobriety and padded walls. But for a HF BPD, who works hard to maintain a facade of stability by strictly avoiding any "textbook" flaws like addiction and suicide, that person is already ultra-sensitive to labels of any kind. Imagine then, how extremely confrontational and unsuccessful it would be to label that person with a disorder like "Borderline." In the mind of the HF BPD, they would justifiably expect that they are being diagnosed as "on the border of sanity," and/or "on the border of a normal society," after all, that's what the average layperson thinks the term means. As long as the label "borderline" is applied to a high functioning individual, I challenge anyone to succeed with treatment for that person. And I estimate that this is a vast segment of society (how many people do you know who have an "estranged" family member?) that is being entirely ignored by the mental health profession.
