INSIGHT

CPTSD Is Chronic Adaptation, Not A Defect

Complex PTSD arises from repeated emotional injuries rather than a single event.
Childhood survival adaptations become adult symptoms like anxiety, shame, and relationship problems.

INSIGHT

Trauma Rewires The Brain’s Safety System

Chronic relational stress rewires key brain regions like the amygdala and prefrontal cortex.
This creates hypervigilance and poor regulation that make past threats feel present.

INSIGHT

The 4F Survival Modes Explain Adult Behaviors

Pete Walker frames four survival responses: fight, flight, freeze, and fawn.
These strategies protect children but become rigid, maladaptive adult patterns.

Relationships after Childhood Trauma: Coming soon

Complex PTSD: From Surviving to Thriving by Pete Walker is a compassionate, practical guide for understanding and healing childhood trauma, CPTSD, and complex trauma. Walker explains how chronic abuse or neglect in childhood wires the nervous system for danger, leading to symptoms like emotional flashbacks, toxic shame, harsh inner critic attacks, and difficulty with boundaries. He introduces the 4F survival responses—fight, flight, freeze, and fawn—showing how they develop as protective adaptations to childhood trauma but can block healthy adult relationships. Healing, he says, begins with recognizing emotional flashbacks, shrinking the inner critic, and practicing self-compassion through “reparenting” the inner child. Walker emphasizes building healthy boundaries, grieving childhood losses, and replacing self-abandonment with self-protection. His approach blends psychoeducation, practical tools, and validation, empowering survivors to reclaim self-worth, safety, and connection. Ultimately, the book offers a hopeful roadmap for healing complex trauma—moving from a life shaped by survival to one grounded in presence, love, and resilience.

In therapy I use a combination of Acceptance and Commitment Therapy, Systems Theory, positive psychology, and a bio-psycho-social approach to treating mental illness and other challenges we all face in life. The ideas from my videos are frequently adapted from multiple sources. Many of them come from Acceptance and Commitment Therapy, especially the work of Steven Hayes, Jason Luoma, and Russ Harris. The sections on stress and the mind-body connection derive from the work of Stephen Porges (the Polyvagal theory), Peter Levine (Somatic Experiencing) Francine Shapiro (EMDR), and Bessel Van Der Kolk. I also rely heavily on the work of the Arbinger Institute for my overall understanding of our ability to choose our life's direction.
