A strange question probably, but do you have a phobia??
I do- I have a phobia of vomit. Seeing a person vomit, smelling it, and vomiting myself (thank god I can't hear!!!). It scares me to death, if I see a person vomiting, it will stay in my mind for weeks. If I get sick and vomit, it never goes away from my mind. I looked it up and it's called emetophobia. At least it's a fancy worded phobia!
