Determine the degree of anxiety from 0 to 10. If 9, 10, use the Grounding technique. With its help you can come to the state of HERE and NOW. Look around, name a few objects that you see, hear and taste. Name one good quality that you like about yourself. Also remember that the intensity of any emotion always decreases over time, so you can simply wait for the anxiety to decrease. If the anxiety is less than 10:1. Realize and verbalize (on paper, perhaps) what exactly you are afraid of. For example: “I’m afraid that the borders will be closed and I won’t be able to travel around the country.” Verbalizing an emotion reduces its intensity.2. Make plans for crisis situations. We are talking about those that you can definitely influence. Uncertainty creates anxiety. And plans reduce uncertainty.3. Focus your mind on factual information. Facts reduce uncertainty. Remember that not all independent media in the world write factual, reliable information.4. If anxiety increases while watching the news, then limit the time for this (3 times a day, for example).5. Focus more on your daily activities. This will help you get distracted.6. Don't make decisions out of extreme anxiety. In this state, you can, for example, quit your job and move to another country, without paying attention to what you are losing, because the imagination is stronger than the real view of things.7. Pass anxiety through the body (sports, walks, etc.).8. Don't try to think positive thoughts or block out anxious thoughts (DON'T THINK). Thoughts are designed in such a way that the more we try not to think, the more we cannot stop.9. Meditation is good for training a more realistic perception of life, and, therefore, reducing anxiety. There are special applications. The goal is to look at the world as realistically as possible. Usually it is not as scary as your imagination. For more details on grounding techniques, you can, for example, find here https://www.marieclaire.ru/psychology/tekhnika-zazeml..
