-Sorry for the mistake I mean't not dissassociation but derealization.

First off I have not been diagnosed with bpd although I have not seen a psych in seven years, I will be seeing one at the end of this month. I could not figure out any other forum to ask this question on other than this one due to knowing this experience is not rare for those with bpd. 

I have been journaling my days &amp; past so I can give the doctor insight into evaluating me. What I am confused/wondering about is my experience with derealization &amp; depersonalization. This experience has happened twice for me and each time they have occured together. This is my experience with it..

The first time it came on I was under a lot of emotional stress due to an overwhelming fight with my partner. We were in his car &amp; I was feeling utterly lost with what to feel/think and was spacing out due to this.

Suddenly I was striken in complete utter panic. I physically responded to the panic with thrashing my legs infront of me trying to push myself away from something. I felt attacked. I litteraly was experiencing the world as if I was suddenly put in a strangers body. I was looking at the situation I was in &amp; at him with absoloutely no recollection or understanding. I couldn't recognize him or recognize my enviroment. 

I could not center myself. I thought I was dying, and I thought I was going to be taken away from the world entirelly. I thought someone else was taking over my body, and as I thought this I started crying and verbally making sounds of fear and desperation. This lasted for about a minute, I started focusing in on his voice &amp; my awareness of him and somehow was brought back to my sense of reality. 

I'll stop there, but the question I have for those that have experienced derealization/depersonalization is this ...
 
Do you experience amnesia when it comes on for the duration of the episode?
Do you loose your memory of your own self/life while experiencing dp/dr?
Can you not recognize where you are, out of nowhere?

The second time it happened to me I somehow managed to save myself from the horrowing experience before it fully overwhelmed me into panicking. At the time I was simply spacing out but to the point I could not bring myself out of spacing out. I was also at the time dealing with a lot of emotional stress, but not specifically at that time. The sensation came back, and I felt myself detaching from my body and loosing my familarity of it. I was loosing recognition on my surroundings, and was so afraid of what was happening I just knew I had to somehow stop it or else I would of started screaming.
