So glad, @blueislandgirl, that you feel better. Did you ask your friend to test too? Did she or would she refuse?

My hope, and that is my guess for all of us with Long COVID, is that you don't have it. There is no rhyme or reason, it seems, for who gets it and who doesn't. I suggest that for a bit anyway, continue to mask when you are around others in crowded places and ask anyone who plans to visit who you know doesn't take precautions to test before they come and, if they have sniffles, to mask. Better safe than sick again.
