To be bipolar do your mood swings have to be fully 4 days or a week or can they be shorter? Because I had depression for 2 days but earlier was depressed for more than 2 weeks. I’m just wondering because my psychiatrist says I’m bipolar which I’m thinking type 2.

How would I know if I’m experiencing hypomania because I’ve had times where I’ve had symptoms but my moods change so fast like seconds to hours.
