Sounds like you're in Stage 2 of the Five Stages of Work. I heard this talk given by a CBC (Canada's National Radio Station) radio engineer as she reflected on her job there:

Stage 1. The Good Day: Your job gives you happiness, fulfilment, and meaning.

Stage 2. The Bad Day: Your job starts to irritate you. Everything you overlooked during the good day begins to stress you. You begin to learn some really unpleasant stuff about your workplace. You become frustrated, confused, and apathetic. You feel powerless.

Stage 3. Revenge: The bad days outnumber the good days. You become self-compensating for your stress. Self-compensation might range from taking home post-its to absenteeism to searching for or even doing a second job during your original job, and worse.

Stage 4. Personal Re-Engineering: You realize that you do value your job. It is the job you’ve always wanted. You explore how you can change so that you can once again have the good day. Personal re-engineering might involve asserting your concerns, negotiating with others, changing your expectations, and much more.

Stage 5. Redemption: Some of your days at work are so excellent, they redeem all the other stress involved.

Anyway, bfx, good luck sorting it all out. We want to see you happy.
