Q: "What am I facing here?"

A: Ennui.

But you probably knew that.

Had a vacation lately?

Have you explored the notion of developing another career?

A former boss told me once, when I was in a fit of pique over something related to work, "Relax man. Everyone has two or three careers in them. You're on your first."

FWIW I went through something you could call a major bout of ennui regarding working in the internet tech sector several years ago. Came out the other end of it just fine, but I work fewer hours/wk as a result by choice, spend more time outdoors, and frequently invest some of it in learning new things. Friends joke that I am going to wind up being that guy in the Dos Equis commercial...

Caveat: I don't have a family to support. Woodshedding and shifting gears is great if you have the financial flexibility. YMWV.

At least take up gardening or something.
