I had two Astra Zenecas. No boost at the time I had covid. I doubt the booster would have made much difference: I've had a couple of friends who were similarly jabbed and boosted. They still got covid and it dragged on for weeks.
Keep an eye on the number of reported cases and deaths, albeit a lagging indicator, before panicking.

It took me five or six weeks to get back to full strength. The worst was a few days. But mild symptoms and fatigue lingered for weeks.
Hang in there. You'll be back to normal in a week or two.
