You just keep riding and do everything you can to mitigate the risks. After my DH did an endo because he had to brake hard when a car turned left into him, resulting in a broken collar bone, we both started riding with front flashers all of the time. We already were riding with rear flashers on in the daytime. Is this a cure all? No, but we both notice a difference in car's behaviors, especially when they are waiting to pull out of side streets.
I do avoid certain intersections occasionally and I modify my commute home if it's at a certain time. DH has rely good skills and is fearless, so he will ride anywhere. But, despite close calls, I am not stopping.Like you, it's our life. Sometimes I feel geeky with all the lights on my road bike, but in the end, I feel safer.
