Using recent findings from neuropsychology, this book shows that who we are psychologically starts with the early presence of an easily aroused fear/anxiety system. It goes on to discuss how clinicians can view people’s difficulties with self-confidence and identity, and how self-destructive patterns can be traced back to these systems and what clinicians can do to help. It also touches on intergenerational transmission of trauma, as well as people’s responses to COVID-19, PTSD, and real and imagined threats.
