An undercurrent of not so good

I feel off. I have for a couple of days now. I don't know what it is with me. I'm happy, for the most part, it's just that there's this undercurrent of something. Something I can't even begin to define, but which feels not so good.

I don't want to go back to that place again. Not so soon. I've only been feeling better a little over a week. I'm not ready to drop back into the hole yet.

I'm tired. I think I'm going to take my meds and go back to bed for a while. Maybe this is all caused by fatigue.
