My doctor actually suggested music for me during these times. I love music, but I find myself screaming to it, not missing a beat, and still thinking just as deeply.

I know this is super silly, but a while back I was at work and I was IMing one of my colleagues who is in another state. I said simply, "Make me laugh." And he IMMEDIATELY responded with, "Boogers." It actually worked. And for some reason, whenever I start getting into those bad thinking modes, the word "boogers" echoes through my head and no matter what, and no matter how stupid, it always makes me smirk. It may only take away those thoughts for a moment, but any time away is good, no?
