How energetic? As if you could run a marathon? Or more like take on several new projects?

Could someone please share their thought processes during a manic and a mixed state? I would really appreciate it. I have always had a small suspicion in the back of my mind that I may actually have bipolar. I have had some hypomanic episodes, I am sure. However, I never, ever feel omnipotent. Self-confidence is always very low. I also have always needed a LOT of sleep to function. Although, I have somehow functioned on 5 hrs sleep during a few periods in my life. I have never been delusional or never had psychotic episodes. I have other features, but I am depressed the majority of the time. However, when I begin to come out of my depression, I have had the tendency (espec over the past three yrs) to "make up for lost time" when I was depressed. I throw myself back into work, school, etc..........only to completely burn myself out & eventually crash.

I don't know. One other red flag is my anger. I wonder, since my anger is so intense sometimes, if that indicates a manic or mixed state (b/c sometimes my mood can change quickly back into depression after being very angry). I hope I am not in denial..........

Thank you for any feedback.
