Husbands sick and I’m panicking

Just 2 weeks ago I was posting about how NV hit my house. My husband managed to side step it then, but just woke up and said he doesn’t feel good. He NEVER does that and I know for sure he’s sick. With my emetophobia, I am petrified of him getting sick (mostly in front of me or me having to hear it). Of course it’s my birthday too. He’s downstairs now and I have the fan on and door closed so I can’t hear. I am hoping and praying that we’ve just been shedding the virus the last couple weeks and he picked it up and this is not a new strain because I actually cannot go through this again. Either that or the crab cakes he ate. Ugh. I can’t sleep now. He hasn’t been sick in 8 years.
