Screaming in my head

I work as a contractor. I hate it. Beyond the fact that I feel like a gun for hire, the place I work at is like this parasite that will continue to suck the life out of me as long as I am here.

If you ever saw the movie "Joe vs. the volcano", you will have a glimpse of how I feel. The movie, which stars Tom Hanks and Meg Ryan, begins with a bleak scene of thousands of workers heading to their office jobs, marching like drones. In the background the song "Sixteen tons" (I owe my soul to the company store). In a later scene, Hanks talks about how he can feel the fluorescent lights sucking the life out of him.

That is exactly where I am at. I trudge into work at a high rise office building with thousands of others. Day after day, week after week. There is no joy or laughter, just workers putting in their time, counting the hours until the weekend, vacation, retirement, death.
I need to do something different, but don't know what. It feels like the bleakness has seeped into my soul. I have tried looking for something else, but I keep asking myself if it will be any better anywhere else. My wife firmly believes that we are where we are supposed to be all the time. Does that mean I am supposed to be in this drudgery? Am I supposed to learn something? Or do I need to be the catalyst for change? And is change even possible where I am? Did I mention that my boss is a micro manager?? Another big issue, but I can go into that at another time.

I need to find a direction.
