Jayme, I found a vast list of phobias here:
http://phobialist.com/
but I couldn't find one relating to competitions or missing the date.
I found a couple that I think must be taken with a pinch of salt:
Arachibutyrophobia - Fear of peanut butter sticking to the roof of the mouth.
Hippopotomonstrosesquipedaliophobia - Fear of long words.
I also found '
dentophobia', but I hardly need to tell what that is.
