Time to give up?

I've come to a decision. On Monday I will not be returning to work. I can't continue. I give up and I am admitting the stress has got too much. Despite my bosses best efforts, nothing is changing. There is a group of people who should be very ashamed of themselves for the way they have made me feel these last few months. I don't know if they ever will, but I'm not hanging around to find out. These bad people are going to walk into work on Monday and discover they don't have a manager for a while...
