Hello, you are SO not alone, I'm deathly terrified of throwing up. Even reading the word irks me. It all started when I was very young, but I thought everyone was afraid of it so I didnt think I had a problem, until three years ago. It has been almost 4 years since i have thrown up, and this time of year petrifies me. However, I practice good hygiene, always wash my hands upon coming home from work, before eating after using the bathroom...i still freak though if I think that it is possible I could get sick.
