I took an antibody test one year after covid and it had not gone down at all. I had no intentions of getting vaccinated while I had my own antibodies. People say that and then assume to still have antibodies but you should test for it. I was also told by my doctor that if I get repeated exposure it will keep the levels up.
Regarding long covid, I worry a lot about that. I had covid for about a month. Instead of breathing issues I suffered terribly from lethargy, inability to focus, and scatterbrainness. For example: I would stand at the kitchen counter to cook but couldn’t figure out what to make or how to make it. I would peel potatoes, cut a few, and start something else feeling unable to get anywhere. I would turn on meaningful minute (as I did every day) and couldn’t listen for more than 10 seconds. While reading a book I would turn on a shiur. It sounds nuts, well it felt even worse. This persisted for 10 months. The scatterbrainness went away after 3 or 4 months but the sadness and lethargy was almost a year. My focus is still down about 5% from what it was 19 months ago but at least I can function normally.
Do they call that long covid? Dont know.. doubt it. But it was debilitated and frightening. And since my covid I have had at least 3 really bad virus/flu bouts (I normally have none).
So if you feel like you can’t shake bits of it, you aren’t alone, but stay hopeful cuz it does seem to clear up eventually. I was really scared it wouldn’t and am very grateful to Hashem for getting back to here.
