 ## Lifespan Integration (LI)
 
 **Core principle:** The brain heals trauma by integrating fragmented memories into a coherent life narrative. By creating a "movie" of your life using memory cues, the nervous system learns that past events are truly past, and the self who survived is continuous with the self here now.

 ## Psychodynamic Therapy
 
 **Core principle:** Much of what drives our thoughts, feelings, and behaviors operates outside conscious awareness. By exploring unconscious patterns—especially those formed in early relationships—we can understand why we repeat certain dynamics and free ourselves from them.

 ## Somatic Experiencing (SE)
 
 **Core principle:** Trauma lives in the body, not just the mind. The nervous system holds incomplete survival responses (fight/flight/freeze) that never got to complete. Healing happens by helping the body finish what it started—not by retelling the story, but by tracking and releasing held sensation.
