you ever have that feeling...

That sinking, pit in your stomach kind of feeling? 

The one where after you've been working on a big project for x amount of hours, you're proud of what you've gotten accomplished, you exit out of the program, and right as you click that little red button, you try to remember if all of that x amount of hours work was saved?

 Today was my turn.

And my 3+ hours of work was not saved.

lovely.
