An excellent thread, lots of good info. BipolaRNurse - yep, very good post.

If I was giving a presentation I'd be sure to include something on what it feels like from inside to be bipolar. Not just the way it looks on the outside. For example, it feels really scary to constantly live with not knowing what kind of mood you'll be in in a half an hour.

As for BP and BPD - someone mentioned what I was thinking - the devaluation/idealization thing is, to me, the red flag for BPD.
