how do I know whether I should change jobs? how do I go about

Apply to other jobs. That's it. You'll have to take time off of work (and maybe lie a bit) in order to attend interviews.

the very thought of that makes me nervous

I've heard that even if you fuck up and end up in a worse job, that can still lead to progress because you will eventually find something better...

If you feel miserable because shitty management it might be worth it

If it's the work itself you should change track

Money isn't everything - I know a guy who became shift leader on a dairy plant, earned mad dough, ended up getting stressed out (fainting and all) and had to go unemployed for a year to get his shit together
