I used to spend about 75% of the time in mania
and 25% depressed. Since I had a psychotic break, due to sustained mania
, it is more like 50/50. Mixed states are the worst and I have only had them a few times. I am not sure it is a FACT than bipolar spend 75% of the time depressed, maybe for bipolar 2, but my observation, it is unique for each person. I would be manic for up to 6 months sometimes, then be depressed for as little as a week or two.
