Doing before feeling

It occurred to me this morning that perhaps I spend too much time trying to assess how I feel. I might feel a lot better if I just went about my work and play without thinking about my mood. As I get active my mood will fall into place wherever it will.

I think I've spent too much time over the past couple of years in a relatively high mood. Now all appears gray, because I have a hard time feeling the happiness I've grown accustomed to. And this lack of happiness is making me feel down. I'm not satisfied with this -what might very well be - normal state. And I'm focussing on the mood, rather than just living.

But this seems to become so much a part of our bipolar existence - this thinking about how we're feeling. Surely this isn't a "normal" way to live. Do "normal" people wake up in the morning and think to themselves, Now how do I feel? Am I up or am I down? Don't "normal" people just get up and start thinking of their plans for the day?

Is it healthy to always be so introspective and focus on our feelings?
