Does anybody find their results or "performance" varies day-to-day, seemingly depending on anxiety or cognitive state, where some usually "safe" situations are tough, and some usually "difficult" situations actually go alright?

I've been suffering from shy-bowel syndrome ever since I can remember. As a child, and growing up through high school and part of college, it wasn't something I thought about or contemplated much, but it was definitely there. Now I'm 26, and it's at the forefront of my mind. In many ways its the worst its been, as I think about it all the time. This negative meditation and obsession with it I believe causes anxiety and helps contribute to whether or not I can go. Likewise, when my anxiety is low and I've been preoccupied with something else for an extended period of time, it's then easier to go; but manufacturing that situation is difficult, as I'm sure many of you know, as it's tough not to think about this.

Anyway, I was just curious if anybody else out there had varying results depending on their state of mind, anxiety, and preoccupation at any given time.
