Just realize that you can be fired at moment from your job and have trouble (if economy) to find a new one. You'll realize how fragile your current situation is, and going through a rough experience will be worth it (to figure out how to make your future more anti-fragile).

Of course most people go through it the hard way (firing, divorce, etc...) But I don't suggest you do it now, but if you are not saving any significant money from your current job you might as well just leave.
