No you didn't because it doesn't exist. The mind is a very powerful thing. Mind over matter and all that. I've been sick too but I know it wasn't anything called 'covid'. Every symptom possible was ascribed to 'covid'. The new 2019 flu jab was the kickstarter for the whole thing.
My daughter worked in a school when they were giving the flumist out and she got pneumonia, ended up in hospital gasping for breath, just by being in the vicinity of that stuff.
