There's also the question of vulnerability. If you've always felt this way, and there's nothing out of character going on, then there's no mystery. I've noticed, however, that I become more 'emotionally frail' when my nutrition, sleep, and training are out of whack. It doesn't happen often, and takes a combination of factors, but I note that I'm deeply bothered by things that I know wouldn't have usually bothered me, and I'm actually surprised at how deeply since I'm usually quite emotionally blunted. It goes without saying that you're coming off a cycle or have been fucking with your endocrine system in some way that you'll be out of character feelingswise.
I only question whether your feelings are out of character because you probably wouldn't have kept your job if you were so troubled by it since day one. Fwiw I'd be looking at nutritional and hormonal causes if you're feeling things differently or more deeply, or are less emotionally resilient to things that didn't traditionally harm you.
