Strip it back to basics.

What is worry? It is when you're compelled to react to a thought with more thoughts. The response is habitual. You cannot let the thoughts sail by without commenting on them.

So the real question is not how to stop worrying, but how to weaken the habit of reacting to specific thoughts.

I think takes time to find an approach that works -- to discover how to both weaken the habit and how to not strengthen it. It's a lifestyle change. Some trial and error is probably necessary.

I don't think there is a magic solution. Try various things, learn how your current mental life causes you to worry. You'll try something, and your worries might increase. So try something else. And when you notice that some change, after some time, has caused you to worry slightly less, stick with it.
