Mark, thank you as always for the response. To make sure I understand what you're saying, you feel like any symptoms I experience probably result from my hyper-vigilance?

Hitting my head is a huge fear for me, as I'm sure it is for many people here. I'm trying to restructure the way I think about hitting my head and get more realistic about the types of bumps that might cause damage. I think, finally, I'm trying to do the emotional work required to confront this deep-rooted fear.

As mentioned above, thank you for the response, Mark. I know this is a very real issue for many people here and I respect and take very seriously the implications concussions and other head trauma can have. Doing my best to live a cautious, but not an anxious, life.
