Exactly this happened to both me and my wife when we caught covid. We were offset by about 4 days, so we got to see each other's decline very clearly. We were both pretty freaked out by not being able to think properly, but after a few weeks we both returned to normal. I strongly suggest trying to worry and think about it as little as possible. It's very very likely that you will return to normal naturally, and worrying will make it worse. This is less certain, but I've also seen brief decline in coworkers who get covid too. They get really slow for a couple weeks, but then return to normal. I think a temporary loss of 15 IQ points is pretty normal for covid.
