I feel like I can't even put into words what scares me. I would say that my biggest fear is others vomiting around me. I don't know if I can say its anything specific other than that. I know that over the years I have been able to at least talk myself down when I know the person is throwing up because of alcohol or car sickness and not because of something contagious. When I worry that I am going to get sick I go into nesting mode. I lock myself in the bathroom and stay there. I close my eyes and I clean over and over. Once at I am at that point I usually go numb and shut off my brain. I have never had to clean up vomit....and I am not so sure I could. :|
