This helps to decrease social anxiety. With this technique, you first imagine a situation in which you were previously anxious, then you write about it, but you reframe what happened. For instance, rather than writing, I was really anxious about being in front of a group of people and totally failed at it, you could write, I've already been in the worst possible situation and now I understand that I was simply overenthusiastic to get that job. Next time I'll approach the interview better prepared.
