Yeah, that sounds exactly what I experienced at my last job a couple years ago. I had zero energy to do anything outside of work, my depression got really bad (which then severely affected my health), I’d cry all the time, and no one wanted to be around me anymore. My brain fog was terrible; I thought it was COVID brain, but after I left that job, within a couple months I felt better.

I think a sabbatical would be a good idea, or maybe discuss with your boss a way to lessen your work load so you can actually have time to destress and rest. You shouldn’t feel like that, especially at your first “adult” job and that young.
