I'm currently seeing a psychiatrist after a recent hospital stay, which was triggered by a period of complete overwhelm and shutdown.

My psychiatrist is trying to work out if her diagnosis will be BPD or Bipolar. My main question for others, in hopes that I can better understand, is this:  


When you experience hypomania, is it sometimes (or has it ever) been coupled with feelings of hopelessness and "internal chaos?" This doesn't always happen to me when I feel like I have a sudden surplus of energy and drive, but it does sometimes when life just feels like it's waaaay too much.

Thank you, greatly, for sharing any of your experiences.
