By definition, Bipolar I and Bipolar II have differing mania and depressive states.

Bipolar I is marked by more distinctive mania which is usually higher and stronger and is more frequently augmented by psychosis than is Bipolar II. The depressions can include psychosis also but the mania is by far the worst of the two moods.

Bipolar II usually has hypomania which is a less severe form of mania and less frequently is accompanied by psychosis but has more severe depression and the depression can frequently be accompanied by psychosis. Bipolar II depression is frequently medicated with a combination of medications including at times an atypical antipsychotic.

To answer your question, I have Bipolar II, so my depressive states are longer, usually. But I never think about what I did previously. I have always taken the best medication regimen that the doctors had to offer at the time so I spend very little time ruminating over past actions. The only regrets I have is that I wish I had been properly diagnosed earlier so that I could have gone further in school than my B.A.
