Earlier quoted context omitted.
I think my point is: yes, the fear is irrational, but you're not irrational because you have the fear. Or saying it the other way, you can't be just rational and the fear will disappear. So it's quite unempathic to think about someone being irrational because he's anxiously, and you don't have anxiety because you're rational.
> you can't be just rational and the fear will disappear. Are you sure? I find that mentally walking through a checklist of true-true facts makes my sweating/shaking/vomiting go away (for a while)
Calming thoughts certainly can help, that's the whole idea behind the Cognitive Behavioural Therapy.
But it might not work that easily for everyone and for every fear, and it also depends how much you're feared, because you certainly can't calm down a panic attack with a few thoughts.
One should just be aware that what works for one person might not work for another.
