What does worry do for you really? Not a thing. It is the menacing What if that causes your head to hurt. Thinking about what might happen and not what is actually happening that creates all sorts of problems in humans.
I struggle with worry all the time. My mom says that I was a worrier when I was a little child. It is in my nature to worry. I have to fight the worry bug when it enters my thoughts. If I leave it there too long it morphs into full blown anxiety. Nobody wants to see that.
Stop the worry as soon as it starts. Look at the facts of whatever the worry is and stick to truth.
There is no cure for worry. It will return but it is easily scared off with true facts.
