Having just been in a accident, I can relate. However, since the bike is back, I'm back too. I was itching to ride (even got on the old mountain bike) and just did it. Last night I passed the place where I got hit and it creeped me out mildly but you just got to get back in there.
I suppose to use an old phrase or saying or whatever: if you fall you have to get back up.
Take it easy, take it slow if you have to, but ride, just ride.
