Kind of freaking out

I have had diarrhea all day, sick with chills, headache, my ears hurt a little too and obviously my stomach hurts really bad. My coworker who I was with yesterday has been v* and diarrhea all night and all day today. I work at a school and so many kids have been v* so I know that’s what this is. But I do not feel n. The last couple times I’ve gotten the stomach bug I have never gotten close to v always just diarrhea and I’m so hungry but I don’t eat anything because I am afraid to. Though now the anxiety is kicking in. What if this time is different?? I haven’t v* in 13 years and throughout my life it has only been about 2-3 times in my whole life. I am not a puker, I’m a pooper as my dad likes to say it🤦🏻‍♀️ actually my whole family is like that. What can I do to keep myself from spiraling??
