I don't know. I think maybe a few years ago. I spent a couple of months only sleeping maybe 4-6 hours a night (not normal for me) and was extremely anxious and irritable. I worked obsessively and felt very frantic/massive sense of urgency but was also very very hopeless and desperate -- kind of an enraged sadness, if that makes sense. I was also kind of socially impulsive (emailed a semi-famous person thinking we could meet up, hanging out with other men, etc.). I also remember experiencing racing thoughts and waves of euphoria that would bring me to tears. But in general the months seem like a blurry mess rather than a series of distinct mood episodes. Does that sound like a mixed state? I wasn't seeing a doc at the time...
