Lemme quote from the wikipedia article:
Emetophobia is a fear or anxiety pertaining to vomiting. This specific phobia can also include subcategories of what causes the anxiety, including a fear of vomiting in public, a fear of seeing vomit, a fear of seeing the act of vomiting, or the fear of being nauseated.  Emetophobia is clinically considered an “elusive predicament” because limited research has been done pertaining to it.
Never knew there was a word or actual … condition for it, but it’s something I’ve always had … my mother has it too. And this is how I know I am not the only one. =) I cannot describe the acute distress that I feel when the idea is presented – no matter the form: discussion, even writing this page is causing me anxiety and making me feel slightly nauseous, I canNOT handle it in any way, shape or form without becoming ill myself.
Also, from wikipedia:
The root word for emetophobia is “emesis,” from the Greek word emein which means “an act or instance of vomiting”  with “-phobia” meaning “an exaggerated usually inexplicable and illogical fear of a particular object, class of objects, or situation.”  Emetophobia is not limited by age or maturity level. There are cases of emetophobia present in children, adolescents, as well as adults. 
And also according to wikipedia, the only “cures” are: hypnosis, drugs (which can make you nauseous – LOL) and exposure are the only ones listed. None of which satisfy my need to “get over it already”.
One GOOD thing is that I have grown older, my fear has become less and less intolerable, the anxiety caused is less and the traumatization from the event (whether my own or others) is less. So maybe one day, I WILL grow out of it … when I am in my 90s.
