Totally man, you're definitely not alone there... so many people I work with, in different parts of the world now just casually drop into conversation "Oh, sorry I didn't get back to you, I was in hospital last week with the flu" - which is wild.
I didn't know this before, but apparently the flu also attacks the immune system, so it super sucks that you've had it twice this year, but I think medically, that's not surprising... but yeah, totally agree, the flu was always brutal, but pretty rare, and now, it's a multiple times a year event.
