Fear is considered an emotional root of all negative emotions and reactions. Anger, hatred, sadness, anxiety, violence, etc. all of them can be traced back to fear.
I lived in fear, and then with fear most of my life. It can't be defeated. And it is needed.
It must be understood and controlled.
Otherwise it will take control.
For me fear is a self conscious and intelligent creature. A monster that lives in our minds. A monster that turns people into monsters. And makes us see others as monsters.
We can feed it or starve it. And it responds. Mostly punish us to do what it desires.
Or
act against anything it is afraid of.
Thing the fear is afraid of most is called love.
