The following days I had mood that I considered not "normal." Normal for me means that I functioned fine throughout the day, with little or no symptoms. This list is in lieu of keeping a regular mood chart.
8/7/11 - mild depression
8/10/11 - brief anxiety, maybe because of not sleeping long enough
8/11/11 - brief anxiety, maybe because of not sleeping long enough
8/16/11 - depressed & anxious
8/20/11 - moody and definitely depressed
8/24/11 - morning hypomanic, late afternoon & evening anxious and depressed
8/29/11 - hypomanic, all day.
8/30/11 - hypomanic, all day.
I was diagnosed with Bipolar Disorder NOS (not otherwise specified), although I consider myself to have some variation of Bipolar Disorder II, rapid cycling. It's not uncommon for my mood episodes to last just part of the day, or 1-2 days at a time.
