Anxiety is all in the mind. It's based off of unrealistic expectations for something that you made as an illusion from your perception of its attributes. So if the thing isn't what you believed it to be, you start feeling uncomfortable, nervous, or even anxious. But since we cannot directly influence things outside of us to that degree, there's absolutely no reason to be worried about it.

Recognize the things that you can change in your life i.e. your immediate surroundings, and make them better. Then let go of the things you cannot change i.e. politics, markets, etc. and learn to follow them in a way that benefits you.
