Good session that ends badly?

[sirtimo]

I went to a B&M this weekend to get away a bit and play some hard core poker. My wife and kids were occupied with a charity event so I had free rein and no deadlines.

Long story short is I played very very well. Made good decisions. Was up some, was down some, back up etc, but the stack size was not what defined the quality of my play. I was very satisfed.

Anyway, at the end of a very long session (about 16 hrs)I made 2 almost back-to-back very dumb plays that left me busto and pissed. By busto I mean my pocket money not my roll and I can afford the loss.

My question is this: I am seeing this whole session, the whole weekend, my whole free "me time" spent as a failure now just because of how it ended stupidly. Having a real hard time reconciling this feeling with the reality that the trip was very very good with a just a few mistakes.

Any ideas? Is this just something I have to work through?
