Before I was diagnosed and put on medication I used to swing quickly between depression and hypo/mania. My depressions were more severe and lasted longer than my manias, so it probably seemed like I was depressed more often. According to my own experience I got depressed always after mania and lack of sleep made me easily manic. So I'd say I had somewhat equal amount of both episodes, but depression was the one that affected me more.

Now when I've been on meds (the ones that have worked properly) my only problem is hypomania, and it's usually so mild that it doesn't cause any problems. Only once during the past year someone got worried about me due to the hypomanic symptoms.

Right now I'm on a new medication and for the past 2 days I've felt the same way when I feel when I'm depressed, but it could be because of several reasons so I don't want to panic yet. But yeah, nowadays when on meds it's been hypomania and rarely short periods of mild depression that I've been experiencing.

I'm not sure, but I think my "natural state" would be mildly depressed.
