I hear you. Up to a year ago I loved my job. Lots of shakeups, changes, and uncertainty in the last year, and now I dread going into work every day. I'm somewhat-lackadaisically looking for new work, but my skill set has gotten VERY specific to what I do here, my "marketable" skills are rusty. And there are a LOT of advantages to this job - extremely flexible work-at-home policy (great for a single dog dad), and the money's not bad either.
My father told me recently that he couldn't sleep Sunday nights, dreading going back to work. I'm not quite there yet, but I know a bit about how he feels.
