Reader query on grappling with tenure denial

In the comments section of our most recent "how can we help you?" thread, Ash writes:

I've been denied tenure. It was unexpected. I've been told that I should just get back out there, write up a storm, double down, push hard.... all to get a NEW great job, and that that's how I'll show them. (Them = the Dean/TPC/few Dept'l colleagues that didn't vote for me, since almost all of my colleagues thought that I was not just a yes but an obvious yes.)

All I feel though is *done*. And exhausted. Thinking about writing sometimes makes me feel ill and other times makes me want to throw things. I suppose that's normal, at this stage in the game. But I think it's possible that it's permanent--that I don't have it in me to start striving and "selling my work" again. Not even for one more year.

I'm not sure exactly what I'd be looking for in terms of advice or discussion; I feel unmoored and I have no idea what to do.

I'm so sorry to hear this happened to you, Ash. Does anyone have any thoughts they think Ash might find helpful? It might be especially helpful to hear from other readers who have been in Ash's situation.
