Hello! I am very confused at the moment because what I am experiencing I'm not sure can be considered dissociation or not. I have looked around and asked my therapist (current and old) but all the facts I've found out seem to contradict each other... I was wondering if anyone here could help me out.

I have BPD, derealisation and depersonalisation disorder (and quite possibly PTSD) I know that I do dissociate, it's been happening for several years on and off... But there are also times where I lose time. For example, I might be on the train and receive news that makes the intensity of my emotion sky rocket and then 'stuff' happens because usually the scenery has changed or the situation has, or I've done something to myself, or people are snapping their fingers in front of my face while I am trying to stutter my way through a sentence (usually my therapist). This happens wherever I happen to be at the time, but when my emotion gets too much. My mind just switches off. I don't know if this is just because I can't recall what has happened or because of something else but this isn't depersonalisation because I feel and see what happens when that occurs. But these events that happen aren't traumatic... I just can't seem to handle the emotions so it isn't dissociative amnesia.

Is this dissociation or something else? Thank you in advance
