Tips for emetophobia? (Vomit phobia)

Marie
Last year, I had a stomach flu and since that, I am emetophobic. My emetophobia turned into germophoby... I don't know if anyone has any tips for that... I don't want to have children anymore because I know they'll have stomach flu and I don't want to be in the same house as someone with that virus, because I'm scared of getting it and vomitting :(
