Can someone enlighten me on what a mixed episode feels like? How does it look to people who are with someone who is having one? What is the best practice for what to do to "defeat" a mixed episode? How long does one last?

My Dx is Bipolar 2, ultra rapid cycling. One therapist told me she'd never seen anyone else who cycles as fast as I do, or should I say, did, before I started good treatment and meds 20 years ago. For an example of what I look like/feel like when I rapid cycle, in the movie Mr. Jones, there's the little Asian teenager in her psych appointment. That's how I am or was.
