I was reading the emetaphobe thread.
I have emetaphobia, but it isn't as bad as it used to be as I have forced myself to stay in the house/room when one of my family is vomiting.
I have a terrible fear of dog poo on the pavement - ironically, I have three dogs and work as a dog walker. It's a fear of stepping in it, particularly if it has been there for a while.
Ugh - getting squeamish and panicky just thinking of it :(
