I think you're handling it well. This spring there seemed to be a rash of people we knew getting hit or having close calls and I starting second guessing what I've been doing. I just keep reminding myself that there is no completely risk free way to get anywhere. Cycling is slightly more risky than driving a car, but MUCH safer than a motorcycle. (If I remember right, its like 20X safer) Then there's the risk associated with having a desk job and not riding regularly...
