I really feel the same. After some long shows i have noticed myself get to that point... I feel horrible and fix my attitude ASAP
Don't feel bad, I do it too sometimes. Especially if I feel the judge was unfair or I didn't do as well as I wanted to. I always feel bad when I get home that day. I'll never forget my first time showing a goat. I was in a class of 11 for showmanship and the girl who placed first came down the line with her goat and shook everyone's hand and said good job.
