Funny you should mention it: yesterday I thought this mixed state was the best state to be in, now I think it's the very worst.

It started a few days, maybe a week (it's not as if your memory is functional under such circumstances) ago, with suffocating depression, the one where you want it to end no matter what, if you see a car or train it seems like an escape. You think about going to a hospital right away if you can even make it. Anger is the only thing keeping you alive. You are very, very hypersensitive. There's anxiety. Lots. Thinking is hard and slow: mentally painful.

Then mania: euphoria, lots of anger, mild hypersensitivity, mild anxiety. And depression again. And so on.

Gradually, two days (again, could be one or three) ago completely, depression has become milder and mania worse: not euphoria at all, but pure ecstasy, no care of dying, connected to everything and everything is connected, every fibre in your body takes in pure spirit, closest to God you've ever been, and depression is bad, but short and at least I can think.

Objectively, it's not the worst I think. Though you become highly confused and your memory is extremely bad. But it feels really horrible and is very, very risky. If depression hits after mania, the not caring about dying and the wanting it to end may merge.

If mood states alternate more quickly, you get this blending of thoughts and emotions, where emotion changes faster than your thoughts can. You can't reason, but only believe strongly one second and something inconsistent or different the next.

Cut-off point is one day: "nearly every day", in the DSM.

I experienced it for 7 years (with sometimes longer unipolar episodes; sometimes more, sometimes less severe).
