Servant's Remorse

It's a classic case of servant's remorse. You regret volunteering to help out with an event because you didn't realize what you were getting into and how much time you would be required to give.

Well I'm regretting the fact that I spent 7 hours last night on my feet after an 8 hour work day, came home with some burns, and got to bed around 1:30! Sigh. And it's not necessarily the time commitment, but the fact that the event was not well-organized or well-staffed. Then there's regretting having servant's remorse! Oh dear I'll stop here.
