I've been dealing with this for the past year, too. We had 2 cyclists die last year, on roads I ride all the time. I hadn't been going on those roads at all this year, even though my city redesigned the whole area with nice wide bike lanes and lowered the speed limit. I've only been able to get myself on the bike really early, and I've been doing an alternate route which has no ghost bikes along the way.

The good news is I finally feel better going the route where the crashes happened. I rode it last Sunday and today, with no bad incidents. I think it just takes time to get your confidence back.
