How do I calm down?

I have a fear of dying. I get anxious about everything and fear of the worst.

I’m scared of airplanes because of the thought of it crashing and dying. But I really want to travel so it’s kind of hard ahaha

My boyfriend and I want to go on a cruise next year but again, I’m scared of the thought of it going down or tsunami or whatever. How do I stop this anxiety??

Even when I go campin I get so scared. If it’s lightening and I go camping I’m awake all night scared that I’ll be struck. I always fear the worst
