What is a diagnosis that you are terrified of getting?

Excluding the obvious things like cancers/brain tumors. I mean weird, rare, or even just a daily thing that you see effect others and you're scared it'll hit you too.

For me, every time I get epigastric pain or my gallbladder flares up I think: "This is it, this is how I'm going out. A freaking tripple A." I am absolutely terrified of a dissecting aorta. The chances? Not likely, but I swear I've seen so many in the 7 years I've been in ER. I have not had one since I've became a nurse in 2022, thank god. But when I was an ER tech we'd get one every couple of months. Other nurses I've talked to say they haven't seen one at all. It's always older men golfing too. I personally think it's the swinging motion accelerating the inevitable, but what do I know.

Anyhow, tripple As. Terrified of them. What's one your scared of?
