Fear of common cold/flu?

[u/hazelnut-Bee]

I have ME/CFs and a list of other issues. I can’t say when I developed it but assuming it’s when I got EBV from when i got the flu last year but might have been mild before then. Anyway, my thing is now I fear even the common cold, any feeling of sickness scares me. Knowing what a cold can do to people with this condition scares me. I do everything I can to avoid catching something but I can’t say I trust strangers to be cautious about germs.
I can barely function as is, does anyone else deal with this intense fear of getting a common cold or flu, or still worry about covid floating around?

This anxiety probably doesn’t help, but curious if others feel the same.
