this is taking over my liiiiife rn

So there’s norovirus spreading around my campus rn. I actually came back home from my uni town cause I’m so scared of getting it lol. It’s just been eating me up inside and I genuinely can’t stop thinking about it and obsessing over if I’ll get sick or not, when to go back, constantly washing my hands which I know is the right thing to do and is ALL I CAN DO but I’m still just convinced I’m gonna get it somehow. My dumb ahh also decided to watch TikTok’s about it and of course it’s gonna be the WORST of the worst experiences, but it freaked me out. Does anyone have any advice regarding how to handle this kind of situation? How do you try and live normally while also being cautious?
