Put things into perspective. If you are a 90% favorite to win a hand, you are 10% to lose that same hand.
When you flip a coin, you are 50% to get heads. You may get 10 heads in a row. That doesn't change the percentage of the next flip. If you only looked at those 10 flips you would think it was a 2 headed coin. However, over the long haul, the odds
are still 50/50.
Point being, don't worry if you got it in good and lost. You did what was statistically correct. In the long term, you will win your greater % of hands.
Let it go, and move on. Don't get mad. I say I am disappointed when I suffer a beat such as you describe, but never mad.
