I've been thinking about doing the same thing. I don't have any grand plans for my PTO, but having just a few days of not work sounds incredible. This virus has made me hate my job, but I think I would hate any kind of work that keeps me stuck at home like this - I don't mind being home for long hours, but I can't stand working here and sleeping here and eating here. I'm with you. I don't think I've ever BEEN my work in the same way you have, but I've always been a hard worker, and I can't be that person right now. That mindset is totally inaccessible. Like you said: saying that I couldn't give the slightest fuck about work is an understatement. I don't have anything to offer you but commiseration. Maybe I'll come to have some complex thoughts about this with time, but everything happening right now has completely drained me.
I don't know that I/we want/need anything other than that, honestly. Deep down I know that I am all good, and not actually suffering from anything uncurable. It's a malaise. It's frustration. It's annoyance. It's boredom. It's the unsettled nature of everything, and feeling like there is no firm ground to stand on. Just knowing others are feeling the same things can be a kind of comfort... a de-isolation... a shared feeling, even if the someone you are sharing it with is some weirdo behind an online username. There are so many fragments, now. Where do we stand on firm ground, any more? "I don't have anything to offer you but commiseration..."
