I finally figured out that mine's not so much a fear as it is ojeriza of sorts -- an intense dislike/distrust of the whole experience, probably in part from growing up with an extremely narcissistic mother and sister and a hypercritical father. Nothing was ever satisfactory, and anything I did, any small acknowledgement came with a string of criticism and/or ridicule.

Figuring it out went a long way toward taking some of the dread out of the equation.

Look deep, find the roots of why it gets to you. Then you can start digging them out.
