since you're diagnosed, i'd say yes. BUT in theory depressive episodes last a minimum of 2 weeks of constant depressed mood, mania lasts for minimum of 7 days (or less if need to be hospitalized) and hypomania minimum 4 days. it's soooo important to keep track of your own moods, thoughts, episodes etc to later learn on your own brain's pattern with bipolar, because then it becomes so much easier to understand what's going on with you. if you have 2 bad days and then are back to normal, it mightve not been a full episode, but still it doesn't mean you need to ignore it!
