I had it last December. It was the worst bug i've ever experienced in my life. I would not at all describe it as "weak and mild". For awhile there, I didn't know if I would survive it. I know several people who died from it.
I also caught it again a month ago. Chills and Fever, two days very sick, but I got over it much more quickly this time around, and it never got as bad as it did the first time.
Low levels of Vitamin D are strongly correlated with the worst outcomes. Learn about this and if you're not taking a Vitamin D supplement, do so. It's one of the cheapest supplements you can buy. Vitamin C, Quercetin, and Zinc are also beneficial. If you're grossly overweight, consider this as a motivational cue to get off the couch and to eat a healthier diet.
Finally, when you do get it, if you're in a high-risk group or start developing any more serious symptoms (e.g., fever) find yourself a doctor who will get you on a real outpatient treatment protocol immediately. If your doctor won't, contact America's Frontline Doctors to get the help you need. Then fire that quack you've been seeing since they obviously don't have your actual health in mind.
I'm pretty sure this is all good advice.
You were fortunate that you got through it, and I'm glad for that. But I stand by my statement. Compared to Smallpox, the infamous "Spanish Flu" that swept the world after WW I, or the "Black Death" of the 14th century, Covid is a walk in the park with survival rates in the 95%+ range even for "at risk" populations.
