I know where you’re coming from. About 5 years ago I suffered a catastrophic fork failure while tooling along at about 17 mph on flat pavement. It took me a long time to be able to ride without fear again—particularly on descents. (On the plus side, it was during the recuperation from that wreck that I bought my first smart trainer and was introduced to structured training).
As others have intimated, time heals all wounds.
