Burnout

I exercised this morning, and I feel burned-out now — like, with my job. Desperately want to go home. But what I REALLY want is to know why/how this happened. Is it a RESULT of exercising? Is it because I have shin splints that hurt? Is it because somebody turned the heat up earlier, and I had to get up and turn it down?

Is it just chemical/psychological? Is Prozac pooping-out on me?

I’m eating lots of whole grains these days, though I’m still generally deficient in vegetables. I get Vitamin C from fruit juice pretty regularly.

I feel violent and angry and just want to go home.
