Random bursts of emotion?

Usually, my moods are very steady and consistent. A week-month fitting the criteria of depression, then a mixed episode, then mania. Lately, my feelings come on rapidly, changing hour after hour. Being hit with random waves of emotion.
Last night I was euphoric. Turning up the music loudly and watching my shadow dance around the room. This morning, I was optimistic and was planning to sew a new dress. But as the day grew later I began to have a significant decrease in mood. At first I was agitated and energetic, but sad. But as I was sitting on my bed, eating a cookie surprisingly all of a sudden it started to taste sharp and metallic and I became overwhelmed with sadness. Just like at the grocery store when a traumatic memory was triggered, but this was deep and without meaning. The world just stopped, and there is no cause, no usual suicidal thoughts, not even hopelessness. Just raw sadness, and the need to just lay in bed with the lights off. Maybe its just my previous eating disorder talking...who knows.
But my moods dont even last long enough to become significant. I just feel lost, like the emotions are rapidly going over my head without even able to grasp them.
I dont know if i've ever felt like this before...I keep discounting what im feeling because it doesn't last...
I just...im so stupid...maybe im just making all of this up...Yeah, all my problems are fake.......

I sort of have something like that, sort of.  When my medication is treating my emotional dissociation half ***ed, since I had that as far back as I can remember, when something happens I can emotionally connect to, for a moment I have a huge rush of a mash of many emotions that makes me laugh and almost burst into tears (my eyes get noticeably watery) and other things all at the same time, but it only lasts a moment or two.  This happened a lot mainly when the emotional dissociation was first treated where I can act on emotions but at the same time they still feel very strange and alien to me.

I know that rapid cycling is common in bipolar but having mixed states can be part of it also. In an agitated mixed state a person can seem angry at the world. When a person experiences dysphoria (which I did before recovery and do now but the cause is not psychiatric) they can have the down quality of depression but seem obsessed with it or focused on it in a manner that has a manic instensity. It would seem impossible to experience mania and depression at the same time but its not and there are a variety of mixed states. Only a psychiatrist could explain specifics of what might be going on with you but you might want to explain all this to one if you do see one so they can better know how to treat you as some medications are specifically helpful on mixed states and rapid cycling but only a psychiatrist would understand the specifics.

Iladvocate is correct about mixed states, I have Bipolar I w/mixed episodes and I can have both at one time. but mine is more like having depressive moods with racing thoughts of suicide or being depressed state and have rages that show up out of nowhere, being depressed and not sleeping for days and still have an abundance of energy, not like a normal depression that you just want to stay in bed all day and have not energy.  Sometimes I tend to get very aggressive and that really scares me.

I do the mixed and the agitated. Unfortunately it is usually when someone I love is agitating me or bossing me or treating me  as if I am stupid. In the last four months I have done it twice. Once to one daughters mother in law and the next to the other daughters mother in law.
Most of the time it is not there, just gets triggered when I feel pratronized.
