That sounds pretty good to me. Heh, I should be one to preach about worry, I am a classic worry-wart (and a ruthless self-critic to boot). Enjoying the moment is almost something you have to do deliberately, it doesn't just come naturally. Kind of like that scene in "Empire Strikes Back" where Yoda sternly instructed Luke to clear his mind of all his questions. It's almost like a meditation thing (and I'm no good at meditation either).
I imagine things will probably be scary for awhile (in the wake of all the drama), and I can't promise there won't be any more concussions. Just hopefully they won't quite be as severe as the big one.
For what it's worth, I think you have a good prognosis for the road ahead. Maybe some of that ice will thaw and the road will get more secure.
