I had a somewhat similar experience. I was doing good work at a place for about a year and got nothing not even a pat on the back. Next year started to get fed up, had a rough patch in my personal life, started getting short, angry and bitchy with people. Ran into technical difficulties on the project I was working on. My idea for solving it weren't listened to and even worse had people listened it would have been a small disaster because my idea was crap. I started staying home either "working" or just plain calling in sick. When I showed up for work people were walking on eggshells around me. So I was an unproductive douche basically. That year I got the biggest raise I've ever had. Don't know why. About two weeks after that I quit.
