So many of our fears, which stimulate anxiety and panic reactions, are about things like this, that we have no control over.
That can sound frightening too. But it can also be freeing, because there is nothing to do about it. It just is. And it is out of our control.
If you like to read, there is a wonderful writer who writes in a calming way and is so enjoyable to read. The author is Pema Chodron and her 2 of her books that were helpful to me are: "The Wisdom of No Escape" and "When Things Fall Apart, Heart Advice for Difficult Times". Small easy to read books, 100-150 pages. Packed with new perspectives, different ways to think about things, and stimulating yet calming too. I found them at Borders, probably are on Amazon
