I am not sure, but that sounds like a more pronounced version of what happens to me when my mania/hypo turns south and becomes dysphoric (mixed). Its like I have all the symptoms of both mania and depression and at any given moment I can feel more of one side than the other, but all sorts of emotions are there wrapped up into one big ball of difficult. My episodes usually stop after about 2 weeks of that feeling so at least I know it doesn't last forever. I hope you feel better soon.

Oh, and like Faerie, I am suuuper med sensitive so I have to take realllllly low dose of lithium 150mg. It does enough to help take the edge off, but doesn't prevent hypo/mania. I am learning what I can to try to temper that on my own, but the symptoms are inevitable so I am learning to ride the wave since I can't medicate to any dose that would actually fully stabilize me.
