Why my job sucks

For the nearly 2 years I have been here, we worked our asses off on a conversion project. While I didn't work nearly as many hours as some of my colleagues, I busted my ass during the hours that I was here. We spent the last few weeks in the last throws of data scrubbing, reconciling the new system with the old system, etc. Then, last week, just as Xenos is about to go live, we were ready, we couldn't have been more ready, they cancelled the project. This was such a dissappointment, after all our hard work, upper management spit on it and tossed it aside. They "may" reconsider the decision in September. This is corporate speak for we have decided it's too expensive, but we don't want to completely tear you guys down. I am so frustrated and bored with this job. Up until now I have kept busy with spreadsheets, data cleanup, etc, now I have nothing!
