Don't know what to do

I went in to work today, just because staying at home is so difficult to focus, can't have anything done.

I've tried to open up the Visual Studio at home, trying to get some framework for the Silverlight & C++ modules up, but still ... way too hard to focus. My mind is racing at 100MPH, ton of questions, but could not find any acceptable answers. Cigarette helps a bit to calm me down physically, fingers less shaking, but still it does not help my nerves.

Don't know what to do!
