This is not what I would describe as Dissociative Disorder. My own experiences with dissociations are to 1) panic associated with instantly feeling convinced I will die or be killed, and 2) the resulting blacking out for a period of time afterwards. I will 'come to' with no knowledge of my behavior/reaction during the period I was out of it. It is as though I go temporarily to another (safe) place.

Sudden burst of anger. I am wondering if you have been misdiagnosed as BP when you are perhaps BPD (borderline personality disorder). Just my thoughts on this. You really need to see your psychiatrist and be completely honest about this.
