Yes, I can relate to that. And, if my experience is anything to go by, it's actually good news...believe it or not.
When are are totally DP'd your brain is trying desperatly to distance yourself from anxiety and panic, and when it fails (and the DP disappears) then you are going to notice that you are nervous...I know I did. But concentrate on the relief that your DP has gone...just give in to your unconscious temptation to start fretting about it...because you know where that will lead. Back to square one.
