I don't really have a baseline. It's hard to pin one down, when EVERYONE has normal mood fluctuations. I know my hypo and manic symptoms, and my depression symptoms, and my psychosis symptoms, and label the vast amorphous combination of things in between to be normal.

I've actually found that once I stopped pathologically labelling every mood I was in, I had fewer episodes. Maybe there was no change and I stopped labelling every day mood fluctuations as more than they were, but in any case, I feel more peaceful, in control. As long as I'm not ringing mania or depression warning bells, I don't care what's "stable" and what isn't.
