Tilt

It is not often that I tilt, but it did happen last night. I played a SNG, and finished in 4th place, that sucked, but it is par for the course lately. Afterwards I played in a heads up SNG that lasted one hand. I was on the winning end when my AA beat two pair when the river paired the board. I then went on to play a heads-up shoot out. I dispatched of my first opponent quickly and was well on my way to defeating my second. I had him covered about 2-1 when he moved all in. I had AQo so I called, he showed 49o, yes 49o. Of course a nine flopped and no Q's or A's, so I steamed pretty bad which the lead to a loss. I then joined a short-handed cash game and lost $20 through complete donkishtiltshit play. I knew that I wasn't at my best, but I still played. Again, I know whey I am making these mistakes, I just need to quit making them.
