I don't think the whole psychological thing is nuts but my experience is that the "science" part is still being developed.

With my PD, it could either be all-about-you or all-about-me. I had an intellectual understanding of that which didn't help a lot. I worked like heck (with my therapist) get to an understanding of a separate self (me) and separate other, which are separate but both OK. Would you like me to write some more about that?

I was hoping Thorn Bird might be around to offer her insight, since you have been helpful to her, but she seems to have flown the coop, after banging on the door, screaming and trying to break in a window to get what she wanted! But maybe she'll come back, we'll see.
