Just thought i'd take a minute to introduce myself before replying to others posts...
I think I've had emetophobia since I was 14 and so many people at school had a sv that they started sending out letters to ask sick people to stay home as well as putting hand sanitizer at every entrance! I was so scared about school for weeks after that. This year I've got it particularly bad, for some reason I'd forgotten about it for a while, I hadn't been sick since I was 12 (now 20) and then I got sick in the easter and it took me by surprise so much (though it really wasn't that bad, maybe because I didn't have time to panic about it before it happened), I think I'd gotten complacent but not anymore!

I think I have this fear because I always used to throw up in really public and embarrassing places as a child - twice at weddings, once in the middle of a supermarket, once on a school trip, once at my tutors house, once in front of people at school.. the list goes on! Wondering if this is a possible theory?
