Hit from behind – not a lot I could do other than not be there. To this day, I certainly feel the anxiety whenever I hear a vehicle behind me. Even after the immediate physical damage is resolved, there's no real accounting for the fact that it'll be with you for a lifetime.
Not wishing to be negative, I now regularly cycle (it took a decade before I bothered to get on a bike again, not necessarily purposeful avoidance, a mix of that and circumstance) though, of course, I'm less likely to take risks and try to minimize aggravating situations (not the easiest of things).
It's not all bad, I learned some ninja wheelchair skillz and I had the best Halloween fancy dress ever. Are those stitches real? They certainly are, my dear.
