It seems like everyone has a different covid path. I was fully vaxxed and caught it at a wedding, but was only mildly sick for a day. The gal I went with to the wedding also got it, and I ended up taking care of her for 6 months, repeated ER visits, nebulizer treatments, enough cough suppressants to choke a horse. She would cough so hard that she threw up nearly every day. The doctors just said they only wanted her back when her oxygen got low, which it did a few times. Getting out of bed and going to the bathroom would get her so winded that she would gasp like crazy. Toward the end she would feel okay for a few days, then right back to coughing fits for several days, it eventually tapered off.
