Here in New York City they have taken to putting up ghost bikes at the locations of fatal cycling accidents. I pass far too many on my 24 mile each way commute. Really makes you think. I believe this retrospection has not only made me a safer rider but also a safer driver. I am routinely shocked at the chances, cyclists, drivers and pedestrians take in this city. Must be something in the water.

I believe your concern will also make you a safer rider. I also think you may be experiencing a sense of your own mortality which would only be natural. Take a break. Give healing a chance.
