This being an internet forum I think half the people probably have it
But ya I can get it too, I think a lot of people get it though, or alcohol wouldn't be so popular. I've found doing a bunch of small things like just saying Hi to passing strangers (when I go hiking) can help.
Edit: Oh I forgot to add this great quote. "I get very tense around apples... Well, I get very tense generally. I think I’ve fallen into the trap of blaming fruit."
