Ugh. I'm sorry you're going through this. I got to that point in my previous job. I felt like that so many days, but I couldn't financially afford to just quit... although I was so tempted to tell everyone to get stuffed and just walk out the door.

Instead, I started looking for a new job. Once I started looking at my options and sending out resumes, the stress at work didn't bother me as much. I felt like I had a bit more control over my life because I knew it was only a matter of time before I found a way out of there. It took two months, but I found a new (much more enjoyable) job with a 30% pay increase. By the time I was ready to resign, I was able to write a very professional, respectful resignation letter. I no longer felt the need to tell everyone off, because they didn't matter to me anymore. I was about to be free from that situation. So, I had a nice, professional exit interview with my former boss, she wished me well and I will have a good reference from that job. I didn't have to burn any bridges and I felt like I was taking back some control over my own life. Updating your resume and taking a look at other options can be very empowering when you're in a job that's making you miserable.
