I don't know the answer to this either! I seem to be predominantly depression with brief and un-plannable periods of hypomania. My psych team is still trying to help me figure out if Bipolar 2 is an appropriate diagnosis for me, as I have had many over the years. I call it "ping ponging" because it can feel just like that. Not knowing which "me" I will be and the constant threat of change, not being able to relax or let my hair down, etc. We have bipolar in our family, but it's a puzzle for me, as I deal with lots of dissociation and don't do well on mood stabilizers.

Wishing all of us well in the quest...
