Work is impossible

I have come to the point where I can say that I can't deal with the manager at my work. He did a performance review today that covered 1/2005 to 6/2006 - He had recorded every error he could find with my work right down to the wrong date on a letter and errors that my coworker had done was blamed on me. He rated my work lower than last year!! I told him that he was trying to push me out the door and that he had succeeded because I wasn't going to take his harrassment anymore. He told me to put it in writing. I told him when I was good and ready! I told him what I thought of him, how he had given me a bad time from day one and that after twenty years with the company, it was odd that someone would suddenly find I wasn't doing my job!! I have lost all interest in working there. I've put two decades of loyalty into that job and am treated like low life. It was a weight off my shoulders to finally say I wasn't sticking around. I should have quit 3 years ago when he took over my manager's job when she retired! This means a lot of changes in my life. I will have to cut back on the ISP I currently have. (Internet Service Provider) I will have to cancel alot of luxuries I have become used to. One has to do what one has to do. I don't care if my work can read this. What are they going to do - fire me??
