I like that bipolar is shorter to write BP, shorter yet. Now... if we shorten Manic-Depressive to MD, does that make us doctors?

Hey, hey! I actually have an answer to this! Try this on:
Emotional Regulation Disorder (ERD)
There are actually a number of names that it is called in various places, but that's the one I heard someone talk about once, and it seemed a good one.
(The basis of where the origin of the term "borderline" is wildly outdated, and I think you guys deserve better. )

Oh! And I like your new avatar!
