Tilting because of a bad decision

[jason_t]

Tonight at Commerce 6/12 I made a read that one of my villains turned me drawing dead or very slim and I wanted to fold. My mentor and many others have tried to teach me that I might fold too much so because of this and the size of the pot I decided to call his raise and fold the river unimproved. I didn't improve on the river and somehow couldn't bring myself to fold. I called, he showed the turned two-outer and I instantly went on tilt not because of the beat but because I was so mad at myself for at first making the right read, backing out of it and making the decision to call but fold the river and then failing to follow through with that plan. This is frankly the worst decision I've made in a long time and I can't get it out of my head. Have you experienced this? How do you get past your terrible errors?
