My psychiatrist has been extremely confused about my diagnosis for a while. She thought I was initially Bipolar type 2, but my manic episodes exceeded hypomanic criteria so I got re-diagnosed to Bipolar type 1. But now, she told me she’s considering the possibility that I may be (rapid-cycling) ultradian. How long does your manic and depressive states (and mixed episodes) usually last? When do they switch? An extreme episode on either end for me can last as little as 12 hours-day to 4 days before switching. Anyone else rapid-cycling here, and any tips?
