Recovering from a bad beating

[KornGeek]

I recently went a played at a 2/4 table in a local cardroom. All night long, I kept getting utter crap, or winding up with the second best hand. After a couple of hours of this, I noticed that I was going on tilt and playing even worse. That's when I decided to call it a night.

My bad playing that night cost me a significant portion of my gambling bankroll.

I'm considering going back and playing again, but I find I'm still doubting myself more than usual, and I'm afraid this could still affect my playing. How do you recover from a bad beating and get back into the swing of things?
