TWF...yes my therapist has spoken about parts before also. Some of my 'parts' are basically coping strategies, probably similar to how you describe the parts that take over when you are triggered.

Idid...yes, I do dissociate to different degrees. Many people talk about that book, I really must get it. Thank you. My therapist is great in that he knows the limitations of research and keeps a close watch on it. He has great hopes for future treatment of trauma, once more neurologically based research is completed.
