I'm going to ask the obvious question: how bad would your life be if you quit? What if you gave your two weeks notice right now?

I'm guessing that one of the problems would be sudden poverty. However, would it really be so sudden? Maybe it would actually be a month until you don't get a paycheck.

Meanwhile your spirits and energy might go way up, which would help you find something else, if only something to survive on. Temp agencies are always looking for people.

I've only once quit a job without having another one lined up, and I've never regretted it. I have, however, deeply regretted staying in miserable jobs just because I didn't have something lined up.

Please know that I'm not judging or telling you what to do. I'm just putting forth some things to think about.
