My bipolar has morphed a few times in my life.

When I was first diagnosed I cycled very very rapidly, with my moods sometimes changing daily. This lasted a few years. Then I had a few years of remission. When it came back, I started having quite long and severe episodes, months and months long. Then this too went away and I had a few years of long but very mild episodes, few and far between. Then in the past two years my episodes became very severe, lasting months or weeks, with marked psychosis throughout.

What's next? Who knows. All I know is that things, at least for me, can change.
