How can you stay calm during a storm

A little rain, I can handle but if it’s pouring and thundering or if there’s a lot of wind, I panic. I will seriously have one long ongoing panic attack u til the storm is completely over which sometimes lasts hours. I can’t be alone during storms. I also have a daughter who passed away after birth and I keep some of her more important things in a backpack like her urn and her hat and stuff and if I go anywhere while it’s storming that backpack comes with me.

How do normal people stay so calm during storms? I literally can’t function, I pace, I panic, I stare out the window. I try to watch tv to distract myself but it doesn’t work much.
