Really fast (Ultradian) cycling, is rapid mood shifts like the ones you've described.

A mixed episode is experiencing symptoms from both poles (depression & mania) simultaneously.

Its not common to go experience what you describe, but it can and does happen.

I cycled a few times a day for 3 months after I quit my meds. It.drove.me.nuts!

So I know how you feel, its exhausting, frustrating, annoying... ugh, I don't miss it at all.

If you haven't always cycled this rapidly, you may want to look into any changes you've made to your meds, or any changes in your life that may have sparked it.

Talk to your pdoc, s/he may be able to help.

Really sorry its so rough
