What part of your job is causing you so much stress? Shitty boss? Too many hours? Bad work environment? Lazy co-workers? Unreasonable deadlines? All of the above?
Once you identify what sucks about your job, ask yourself "can I change it?" The answer could be no, but if there's anything you can change to make things tolerable, do it. Maybe it's finding an interesting project, maybe it's transferring somewhere else within the company. Do what you can to make things better, then try to tolerate the rest.
Lack of job satisfaction is pretty common, but if you actually hate your job, to the point where it's negatively impacting your personal life, you may have no choice but to get out.
