Hello friend @sandracarrascal, we can say that fear is a feeling that accompanies us always more than others, but, we all feel that sensation, it is important to highlight what you express:
Fear can bring a state of confusion between facing or remaining passive and neutral, in this situation we must evaluate what really causes us fear, because even sometimes fear can save us from an eminent danger.
This is really true on many occasions feeling fear allows us to avoid some dangers that are presented to us.
Exactly the fear allows us to be persuasive in the face of a threat, greetings and thanks for commenting @rbalzan79
