Hiya, I am from a different train of thought to Christina. I find many people who claim ultra rapid cycling tend to be reacting to triggers rather than an out of the blue mood episode. A trigger can be as simple as a thought and your mood can plummet. Best to talk to a therapist to sort out the triggers so you can better deal with them and not have unstable moods throughout the day.

If I claimed a mixed episode everytime I had a day like yours I would never be out of it EVER! My mixed are always pdoc diagnosed (as I tend to be on the lower side I think of it as depression but pdocs set me straight usually by a hospital admission) and tend to be dysphoric and dangerous. Everyone I have met (in real life) with mixed episodes has ended up inpatient as it is constant terribleness (for lack of a better term!)

But I am most certainly stable but stressed at the moment and I react to triggers- ie mood plummeted after being happy and talking to a neighbour. Neighbour had suggested to move my stuff to his shed.. all well and good but I got stressed out as I didnt have the physical strength to move things alone - so my mood dropped as the thought was "I am a failure". Now 3 hours later I am out of that mood with CBT techniques and distraction with other activities. That is NOT a bipolar mood cycle, simply me reacting to a trigger while distressed. Since I have the tools I have "stabilised" easily and moved on with my day. Can you relate?
