It hits me in little clumps and can change according to what I'm thinking or have dremt about in my sleep.

One day I'll be fine-or at least, I'll think I'm fine but then I wake up the next morning and everything in my life and what is not in my life is validation enough for me to stay in bed for the rest of the day. It could last a couple of days to a week but then one day I wake up again and I'm fine.
??? These aren't major or very serious depressive episodes either so that may have something to do with it?
