I work as a systems and database administrator and sometimes my anxiety gets in the way of my productivity. When we have deployments of new software I tend to freak out and start to play all of the bad events that can occur in my head. I still go through with the deployment but I keep thinking what will happen if something goes wrong and I can't fix it.

I'd like to believe there are others in the same boat. How do you handle your anxiety when you are in IT?
