Space Anxiety

I don't think its normal when for a week, my mind doesn't want to stop thinking that a certain space rock (not world ending) could impact close to where I live. Even though the simple chance of it hitting earth in october is 1 in 11 million, there's so much uncertainty regarding it, that my mind constantly wanders into: "It'll end me, it'll end me, if it hits it will only hit where 1 live" even though the most calculated path of it is showing it going to the bottom (southern hemispheres) of the planet and not at the top part (northern hemispheres where 1 live). Im just scared it's uncertain to the point that the odds are just some calculation they did based on some data that there isn't a lot (even though these calculations have all of these uncertainties calculated in them) and I just can't stop worrying it'll hit where 1 live...(may have typed this in already, but Im just anxious over the top)
