Janine - and this is slightly off topic, though you have touched on it a couple of times in this thread: you seem to have a theory that explains these strange sensations. You even offer a "cure", here and elsewhere on the site.
Now, I am not trying to be argumentative. You know I am not like that.

However - there are many of us seemingly stuck in this mess. What you offer as the way out suggests a choice is possible. That if we were to become less introspective, focus outwards more, become more involved in the outside world rather than our inside world, to stop trying to control everything..........that somehow, if we only made the choice to do these things - we would come out the other side of this nightmare.
While that is a gross simplification of what you try to say, I think it at least hits on some of the high points.
My question is: if we have this choice, this ability to to change - why don't we? Isn't it possible that, for some of us anyway, this is NOT a matter of choice? Because I can't help but think every person on this site would make the choice if it was possible. Would sit down and think, "mmm, today I think I will be less introspective, will become more involved in what's around me rather than in me, will try to be less controlling of those things I have no control over......"
Again, not trying to be a brat here or anything. Just pointing out what to me is very obvious - the inability to CHOOSE to be otherwise may in fact be a large part of the illness itself.
This is where the nature vs. nurture conflict arises for me. I seem no more able to choose not to be DP than I would be able to choose not to have cancer.
And more descriptions please. Thank you Wendy, Dalai and Snowy.
