Mood instability and extremity is an oft-discussed feature of BPD, as is its comorbidity with Bipolar. But people rarely talk about the ups like they do the downs.

BPD is mostly associated with a spectrum which has depression at one end and obsession with a new person or identity at the other.  Really people just seem to talk about the depression. Do you experience Euphoria as the opposite of your depression within you mood instabilities, or is it more complex than that?

Those of you that are bipolar, how does that go down in regards to the up periods? For me I really convince myself of a slightly different concept of self for 5 days-weeks when I'm hypomanic, in addition to the other usual hypomanic stuff. Normally my varying chosen identities are more fluid, or more aware. When I'm manic I can really buy in, and it makes it feel worse when I come back down.
