Some situations are born out of emotion, and one way of dealing with them is by applying logic. You write down all the emotional triggers that led you to where you are, and you demolish them, one by one, with cold, ruthless logic. "Was that true?" "The evidence indicates that it wasn't." "Why did that happen?" "Because someone was acting on signals which may not have been intended." "How come somebody said what they did?" "They felt it was true at the time." "Would that really have happened?" "No." And so on.
It doesn't work very well. But at least you know that whilst the emotions will fade away, given time, the cold ruthless logic will endure.
Some of you know what I'm talking about. Others will just have to guess.
