Does anyone else think they had Covid, before Covid was a thing?

I keep thinking back to this "flu" that I had about 4 years ago.

Worst **** I ever went through, I was at the gym with my buddy, tried to do some squats and just had zero strength, other than that I felt fine so I just sat the session out while my friend trained.

Got home and within an hour **** got real, I had an insane fever, throat like razors, snot gushing out of my nose, legit could barely breathe, I was actually TOO AFRAID TO SLEEP in case I stopped breathing, and sitting there at 3am pondering calling the ambu lamps.

I spent the next week living on the couch in various degrees of the previous symptoms, one time I tried to go for a quick walk round the block for excercise and LITERALLY SHAT MYSELF.

took me probably 6 months to regain full strength in the gym, flu my ass.

So yeah I'm pretty sure I had C19, in 2017.
