Please take a look at the book, Transcending Trauma: Healing Complex PTSD with Internal Family Systems by Frank Anderson.
“Complex PTSD, in its most basic form, is a relational violation that disrupts our sense of trust and safety in the world and limits access to our Self-energy. Healing relational trauma puts us back in touch with our natural core and permits us to love and connect again with others.” ― Frank Anderson, Transcending Trauma: Healing Complex PTSD with Internal Family Systems
“It is unrealistic to expect that people who have been violated by relationships will expose their vulnerabilities to a total stranger without repercussions. Under these circumstances, traumatic reenactments are practically unavoidable.” ― Frank Anderson, Transcending Trauma: Healing Complex PTSD with Internal Family Systems
