It's tough. There was a rider killed not that far from here a couple of years ago and there was a vigil held for them. I think about them every time I go past the ghost bike.
13 years ago I lived in a rural village, and I should have been killed on the unlit A-road when someone drove through me from behind (I was well lit, as evidenced by all the cars and the bus that overtook me safely), and a few months later I ended up having to commute along that same road - it was very unnerving every time, but in the end you just have to grit your teeth and get on with it, since there was no alternative route, it was either that or give up.
Now, years later, I can't even look at that road on streetview without feeling nauseous. I certainly won't ride it again.
It took going on an organised night ride with other CCers/YACFers to make me comfortable with riding at night again.
