There's a form of bipolar called mixed state, where you have agitated depression, lethargic mania or hypomania, obsessive thinking and a general feeling of disconnectedness. I have treatment resistant ultradian cycling(several mood shifts a day)/mixed state. As everyone else has said, if what you're experiencing is problematic, you'd best bring up your symptoms or manifestations with your doctor. The worst thing you can do is think nothing is wrong or think you can handle whatever's happening, then end up going off the rails. Take it from someone who goes seriously crazy every few weeks.
