I don't track my moods, never have, but I think I should start. I know what you're saying. My best friend noticed something that my long time (15 years) pdoc and I never did: I tend to get hypomanic in the Fall. I can see it now that she pointed it out.
Don't know the answer, but my sense is that our own perceptions are also important. No one else knows how feel inside, they can only see our behavior.
