I've been diagnosed with it. It took me a while to realize that I was experiencing hypomania. I get incredibly black and white, irritable, impatient, mad that no one is good enough or can keep up with me, overly confident, excessively talkative, bouncing off of the walls, hyperproductive, rapid speech, insomnia, alcohol abuse, hyper sexuality, some reckless driving, and some reckless spending. I don't experience everything at once and may have left some stuff out. I have no idea why they call it a "mild" disorder because it is anything but mild. My depressions don't qualify me for bipolar I or II because I'm not (or have ever been) suicidal and I can still get out of bed and do things (90% of the time). My depressions don't bother me too much when I am around people that I like, but alone, I am incredibly tearful (often to the point where it is debilitating, hopeless, unable to enjoy things that I typically like, unable to sleep, a negative talker, self-loathing, convinced that I am hated by all and utterly hopeless. My agoraphobia and anxiety can act up in these times. I hope this helps.
