For myself, I notice that if I'm irritable or agitated for a number of days I feel really disconnected and dissociated and can not relate to my other self one bit. I become a totally different person and also feel like I'm not really experiencing what is happening (ie. looking at it from an outside perspective). And I get thoughts that I would never have otherwise (hate my family, perpetual pessimism towards the World, etc.)

I guess anger is just one trait among many that can trigger dissociation (or maybe I'm on the wrong trail altogether since I also have a mood disorder)?

No PDOC or Psychologist has ever noticed this in me over last three decades (as inpatient or outpatient) which really frustrates me. And I've seen a lot of them, believe me.

I self-diagnosed this over the last year and brought it up a few times with PDOC. He told me that he knew 3-4 PDOCs in 1990's who treated dissociative disorders and he discovered that the PDOC usually knew more about the patient than the patient knew about him/herself.
