Jekyll and Hyde Syndrome: What to Do If Someone in Your Life Has a Dual Personality - Or If You Do Book

I'm sure the author has done much to help many people. Arriving at her conclusions from within a Jungian psychotherapeutic approach, she tends to take the view that integrating one's shadow side will bring the extreme parts of the personality to awareness and (positive) fruition. While I think the approach would be valuable for many, I would doubt its value in cases of diagnosed BPD and NPD. These are mental illnesses, not simply evidence of a fractured personality and there are evidence based modalities which can assist in symptom management. The person who splits, sees others as all good or all bad, would, at least from much other work that I have read, find little relief from this approach. Overall, however, an interesting read, and that we all have good and bad aspects which at times can be denied or projected out onto others is at times a reality. A worthwhile read.
