Daisy - that whole idealizing/devaluing thing with BPD has never cut ice with me. Because we all do that to some degree in our relationships. You seemed fond of RoboT in your posts on here, but not idealizing. And my sense is he hasn't been too present for you the last couple sessions, so I wouldn't call it devaluing. I would call it your valid reaction.

As for BPD in general, I don't know if you want a diagnosis of it or not - I get the sense not. But the more I read about it the more skeptical I am of it as a viable diagnosis. It is not as cut and dried as DSM makes it out to be.
