Are you on any medication? If so it appears that they are not doing the job obviously. Have you contacted your Pdoc? How is your sleeping ? Are you able to eat? Work? Can you carry on a understandable conversation with others?

You could very well be Rapid cycling but that actually means more than 4 distinct episodes in a 12 month period.

Ultradian cycling means Yes you can have numerous mood shifts in a single day ..but, its very very rare to be honest.

I am no medical doctor of course , but I would think a Mixed episode is more likely. Mixed episodes are literally pure hell on earth.

You really need to contact your Pdoc, "usually" they will hit it hard with an AP of some kind to knock it down, Or make adjustments to your currents meds, doesn't mean you will always need "that Ap"( if one is prescribed) But it just can help put an end to the pure hell.

I'm really sorry your in such a horrible place. Please get help from your Pdoc as soon as possible. I know its Holiday times and your Pdoc may be unreachable, so worse case you can go to your ER. Most Er's are not thrilled to mess with any psych meds to be honest but if your not sleeping ( which is a huge distablizer for Bipolar) they may in fact prescribe a sleeping med to help you until you can see your Pdoc.

I hope your able to get help ASAP, My heart goes out to you .
