Why is it so hard to stop playing when on tilt?

I notice the more I lose, the more I tilt. The more I tilt, the more I want to keep playing for a win to make me feel better.

The promise of a win soothing the tilt and the gamble of a loss driving me ever closer to the edge of madness are both unnecessary. Tilt will always taper off over time, with or without a win. Furthermore, under such a burden, I'll inevitably make irrational decisions that'll further compromise my chances of winning.

With that understanding, I wonder why it is so difficult to pull myself out of the loop. To simply stop playing and come back later after the tilt resolves on its own?

Coming off a 3 game losing streak, I really had to place forth some willpower to acknowledge my tilt, drag myself out of champ select, and accept the notion that I should cease my pursuit of a tilt ending win and write this thread as a way of cooling off instead.
