When nothing happens, I mean when you don't want to take part in those useless time-wasting activities. Read more books. Reading more books can really make people feel calm. Making a cup of coffee and reading in the afternoon sun is a very quiet and happy thing. When you are cheerful and calm, you can't be confused naturally. If you don't want to study, don't surf the Internet. That will only make you more uneasy.
You can do physical relaxation exercises anytime and anywhere. Choose a comfortable posture, or sit or lie down.
From head to toe. Let the muscles be completely tense first, and then relax a little. Be sure to slow down and take a deep breath.
This will calm you down. Now you can have a try.
The gentle rate of deep breathing should not be too fast. Expiration time is longer than inhalation time, and the gas is completely discharged every time you breathe.
Eat more bananas and tomatoes.
I don't know what the specific scientific truth is, but bananas can make you feel happy. I just know that bananas, known as the king of anti-anxiety drugs in fruits and vegetables, have a good calming effect on stress and anxiety in life.
I suggest you have a try.
If there is a problem, you should overcome it. In the end, everything will work out. Even if the problem is not solved, it is better to calm yourself down and give yourself a space to change your perspective.
