@Lelivre It was so mild, almost to the point of being asymptomatic. I just chilled out at home and even did some light exercise in my bedroom. The aftermath was shocking, and left my life in total wreckage. I think I read somewhere that most people with Long COVID - not those with actual visible organ damage, but those with a post-viral fatigue type of illness - had a mild infection.
As to what helps me - it's hard to say. The key is just rest, rest, rest, don't ever overdo it or push past your limits. Other than that - drinking a ton of water, taking the few meds/supplement for specific symptoms (sadly none really help with the fatigue or exertion intolerance, but can help to sometimes just feel more "well" in myself on a day-to-day basis), and for me personally, trying to hold on to the hope that maybe one day, even if it's in 5 or 10 years' time, there'll be a breakthrough treatment that'll restore my - and millions of others' - quality of life again. I'd like to think that's not that far-fetched, but it's pretty hard to keep believing it at times. When I feel especially low, I just read some of the new and incoming research.
