I am an extreme emetophobic. I realized this about 2 years ago. My emetophopia gets to the point that if someone in my family is sick, I will lock myself in my room and spray the entire house with Lysol. When it gets really bad, I even refuse to eat so that I have nothing to throw up should I get sick. I tell myself that throwing up or vomiting isn't as bad as I think, but I can not get myself to believe it. It messes with my life.
