What is fear and how to get rid of it?

And it is important to distinguish fear, like when you see a wolf coming towards you, from fear when a loved one leaves after 20 years of living together. When he/she says these words, the world turns upside down in the same second and it is very difficult to cope with yourself, to calm down. The most serious sedatives come into play. A person finds themselves on the verge of life and death... it's as if they are being torn apart. And you seem to understand that you need to do something, but the body seems paralyzed and subject to the will of something invisible. And the hardest thing is dealing with your thoughts(!) because they lay the foundation for all the ensuing events.
