What CPT is
Cognitive Processing Therapy is one of the most studied treatments for PTSD. It focuses on "stuck points": beliefs that formed during or after trauma and never got updated. Things like "it was my fault," "I can't trust anyone," or "if I relax, something bad will happen."
We look at those beliefs closely, check them against what actually happened, and build more accurate ones. The memories do not disappear, but they stop dictating how you see yourself and other people.
