I just went through a six-week depression, which is pretty abnormal for me. Typically, my moods are ultra, ultra rapid. My pdoc diagnosed me with bipoar NOS, he said I seem like an ultra rapid cycling-type. Sometimes my moods cycle so fast, I'm not sure if it is part of the bipolar or not. For example, yesterday I felt kind of down in the morning, not too bad.... Then I was ok, then at night I started going up, up, up.... couldn't stop talking, laughing a lot, then started getting really agitated until the point that I felt sick. The "up" wasn't a good feeling at all... So uncomfortable, I didn't know what to do with myself. Eventually took a Klonopin and was able to calm down after awhile. Today I feel pretty normal. Does anyone go through really brief and/or rapid mood cycles?
