No, it’s nothing you should be worried about.
The Earth is constantly being bombarded with rocks and most of them burn up in the atmosphere way above our heads and will never cause any harm.
A few rocks make it down to the ground, but the chances of being hit by one is basically non-existent, and these are typically very very small.
However if a really big asteroid were to collide with the Earth it would be very bad. But that is also very unlikely and even if it were to happen it would be so catastrophical that there is no use worrying about it.
An asteroid big enough could easily wipe out an entire city and if you happen to be in that city there’s nothing you can do anyway, it would be comparable to a nuclear strike, which is probably more likely to happen.
An even bigger asteroid could wipe out humanity and most of the life on the planet, just like with the dinosaurs. Again, if that were to happen theres literally nothing you could do so there’s no point in worrying about it either. Also this is extremely unlikely.
However astronomers around the globe are currently tracking all known bigger asteroids and other objects close to earth that could pose an issue. Although there isn’t much we can do if one of them are on a collision course with Earth, but we would at least know about it.
In short there are a lot more common stuff you should worry about. You are far more likely to be in a car accident or slip and fall in your bathtub. So make sure to always wear a seatbelt, drive safe and be careful when getting in and out of your tub (if you have one).
