Kind of similar but not, I once folded AA on accident, and two guys after me got it in with QQ and TT. I was pretty pissed at the time b/c I was playing awful and on a huge downswing, and I was really tilted after that hand. But then I realized that even if I had won the 2 BIs, what difference does it make. Obviously it sucks, but in the long run it's irrelevant.

What's important is that you realize you made a mistake, you double check with others to confirm that it was a mistake, and then next time when in the same situation, play it correctly.

In the long run, the extra $ you would have won in that hand is completely irrelevant. Never forget that poker is all about the long run.
