I'm glad you're feeling better physically ssp- that was one hell of a crash. Most of us who've had a serious (or even not so serious) crash can relate to your mental state. I remember one I had a year ago- bike vs. bike broadside at 30mph (I was the hitter)- it took a couple of weeks to get over re-living the instant of impact over and over. It was weird, and very visceral. Basically minor PTSD. It helps to talk it out.

All the best for a speedy recovery, and to your wife and buds too- I'm sure it wasn't a pretty experience for them.
