"DEPERSONALIZATION DISORDER
Persistent or recurrent experiences of feeling detached from, and as if one is an outside observer of, one's mental processes or body (e.g., feeling like one is in a dream).
During the depersonalization experience, reality testing remains intact.

The depersonalization causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

The depersonalization experience does not occur exclusively during the course of another mental disorder, such as Schizophrenia, Panic Disorder, Acute Stress Disorder, or another Dissociative Disorder, and is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., temporal lobe epilepsy)."

Sorry to come back to this, but I am just trying to make some sense of what happened to me the other day. I have done nothing but think about it (until it got to the point that I had to take some of my meds to shut my brain off from thinking!) adn I am still really confused. I can't see my nurse til later next week either otherwise I would have talked to her about it and gotten some perspective. The above quote is from a link KD gave me to 'investigate' recently and it fitted but not like it does now. Where it said about being an outsider looking in is exactly what I siad to my t the other day.And that's the part that I kinda still don't understand. It says that 'During the depersonalization experience, reality testing remains intact. ' Is that why I am aware of what was going on, of what was being talked about although it felt like I was watching myself do it rather than 'actually being there'? And about the 'losing time' bit- would that be because had 'depersonalised' and was 'watching myself' rather than 'being there adn being me'?- (it is so hard to explain!). (and just for my information, as I know nothing about it, if you have DID are you aware of everything that is happening, or is it really 'lost time' that you cannot account for, have no recollection about,and you know nothing of what happened while one of your parts is out?
