Well no, comparisons like that are productive:
you were FOUR times more likely to be struck by lightning than killed by a terrorist

OP is asking how to deal with the fear, well the fear is highly irrational. Is OP scared of lightning all the time? No. So why terrorism? It doesn’t make sense.
A good example. I’m from Amsterdam. The central station is probably a big target for terrorism now. It’s the most iconic place of the city with locals and travelers alike.
To be there at the same place if there’s a terror attack means I have to pick the right day and time. Since I’m only passing through there for about 5 mins in, then entering the train, or 5 mins out. It means I have a 5 of 1440 minutes per day chance in the day that terror strikes or 1 in 288. Now let’s say nothing happens for a year and then one day a terror attack strikes. That means 1 in 288 * 365 days or 1 in 105,120. That is, if we’re confident it will happen in the next 365 days which is also unlikely.
The risk of me dying in a car (even with a seatbelt) in a year is 1 in 17,625 (http://www.riskcomm.com/visualaids/riskscale/datasources.php).
I’m still 6x more likely to die in a car accident than a terrorist attack at the central station of my city which is a terrorist target ONLY if we’re sure it’s going to be hit this year.
Furthermore, outside of that “the chances of being killed in a terrorist attack are about 1 in 20 million” http://www.lifeinsurancequotes.org/additional-resources/deadly-statistics/
Why is it important to mention the statistics? Because it’s rational. And it doesn’t give us an emotionally skewed perspective on a highly unlikely scenario. Which in turns influences politics, war and the increase of a commercial security industry. The question is, do you want to highly armed guards everywhere? Do you want to live in a society like that? I don’t.
