Fear is the mind killer, the little death. − Frank Herbert
The Nature of Fear
Fear and all of its gradients−panic, alarm, anxiety, worry, concern, nervousness, trepidation, caution, etc.−are all different levels of angst over the loss of the sustenance and/or the enhancement of life. Fear in its most elemental essence is simply the opposite of worship because it grants credit for the possibility or intent of detracting from or eliminating the sustenance and/or enhancement of life. See the definition of worship.
It is rather easy to see and understand the above definition and the unproductive nature of these aspects of fear when they are not legitimate. Illegitimate fear is debilitating, such a needless waste and theft of life fulfillment and enhancement. All for no reason!
The challenge comes in two phases when it is time to deal with the gradient of fear when it comes to us. First determining whether that aspect is real, substantive, valid, legitimate. If it can be determined that the fear is not legitimate, no problem because the fear can then easily be dismissed.
Secondly, when the aspect of fear is genuine, has substance, how then to manage the negative effect upon the best course of action? It is widely understood by reasonable people that the worst thing to do is to deny it or bury it. It is mind clearing and empowering to acknowledge it and yet not be controlled by it.
"We have nothing to fear but fear itself!" Franklin Delano Roosevelt
You could write a book about it but the simple solution when fear comes unbidden is to own it, admit that it may affect us, but,determine NOT to be controlled by it
