As a way to deal with worrying I recommend writing down everything you worry about. The article This Simple Task Can Help Curb Your Constant Worrying has the same message.

“Writing down your thoughts and worries makes you feel lighter because you’re getting rid of those worries that are weighting you down.” You’re also getting distance from them. “When you take a look at what you’re worried about, it’s often unrealistic things,” says Schroder. “Getting the thoughts out of your mind and out on paper is helpful.”

I actually recommend the following process.
1. Write down everything, big and small, that worries you. Use pen and paper, that stimulates more of your brain.
2. Read the Serenity prayer, it’s excellent guidelines.
3. Cross over those items on the list that you can not change or that are unrealistic.
4. Take a look a what’s left. Are they all things that you can change?
5. For each item that’s left, set a date when you shall act on them. Our brain lets go of things that have a date attached to them.
6. Act on the items that you can change.
Repeat the process above each time you worry too much.
