I had Covid 6 months ago. Wasn't too terrible and responded well to treatment, but ever since then I've had a continuous stream of bad colds. Each month has been on average 2 weeks healthy, 1 week feeling run down, and 1 week sick. I ended up missing a solid month of HEMA classes and had to get a friend to teach my BJJ class for me on multiple occasions.
Anyway, the reports I've seen online say that Covid can mess up your immune system for 6 months post-infection and it's been 6 months now, so I'm really hoping that I can finally stay healthy for a while. Fingers crossed.
