"Lightening striking twice" springs to mind here I would say
Easier said than done, I know, but consider how many years you have been riding and how many accidents you've had in that time, if any (apart from this one). Keep telling yourself this, luck is actually on your side
Perhaps not entirely the same but when I was younger, before having a license of any description I used to pedal bike it everywhere. One night I was knocked from my bike when a chap drove out of a junction straight into the side of me, this was on a busy main road and I was catapulted across to the other side of the carriageway bounced with my head onto the grass path/verge the other side. I encountered death rather closely here as a 17 tonner was on the other carriageway and had to brake very hard not to crush me as I flew across his path. Anyway, long story short, I took the advice I have given myself and jumped straight back on the bike, well a new one as the old one was rather slightly mangled
Never had another incident on the bike!
