There's a great deal of truth to this. T is a blank slate ready for you to write whatever you need to write, and in that way you act out your worst fears.

It's like there is a stone in the room and you say "That stone is a spider" - because you're afraid of spiders.

How do they get you out of it? They expose you (or more accurately you expose yourself) to your fear over and over again until you get used to it and it's not so scary any more.
