I'm a voracious reader, so I always take a book with me to my T's office. Generally I have my nose in a book while I'm sitting there and I honestly hardly notice all of the other people around me. Don't know if distracting yourself that way might help, but at least you wouldn't spend your time looking at all the other people, and if your mind is occupied with a great plot maybe your thinking won't try to "go there" so much. (Just a thought. I realize not everyone is a voracious reader.)
