I also realized that my worrying/obessing actually CAUSED some bad things to happen.
I also used to be a worrier, I don't think I obssessed over it but I did worry quite a bit about things like losing my job. BD was something of a revelation for me in the worrying department, because of all of the things I worried about, my marriage was not ever even on the radar. It was my home base, my wife was the rock in my life that I knew I could always depend on. HA! So the revelation for me after BD was that the things I had worried about in my life NEVER happened. It was always things I didn't worry about that came up to bite me in the butt. It was like something clicked in my brain with that realization, and now I don't worry at all. Whenever I feel some worry creeping in I just remind myself that if I'm worrying about it then chances are it will never happen based on my track record, and that immediately makes it go away. Works for me.
