Fear is the natural response when we feel out of control. However fear weakens and paralyses so we need to rid ourselves of it. 

How? How does one just stop fearing? Is that at all possible?

The answer is no. You can't just switch off fear but you can switch fear for something else. 

There is another word that also begins with 'f' called 'faith'. Faith has the power to replace fear and give us strength.
