Fear is a powerful and fundamental human emotion. It alerts us to the presence of danger. Fear can be divided into two things, biochemical and emotional. The biochemical response is universal, while the emotional response is highly individualized. The emotional response to fear is personal to what you’ve experienced in your life.
Some people like adrenaline and do activities that will get their adrenaline and fear high. Other people have a negative reaction to the feeling of fear, avoiding fear. Although the physical reaction is the same, fear may be recognized as either positive or negative. Repeated experiences with fear leads to familiarity. This greatly reduces both the fear response and the resulting excitement, leading adrenaline junkies to look for new and bigger thrills. One aspect of anxiety disorders can be a tendency to develop a fear of fear. Where most people tend to experience fear only during a situation that is perceived as scary, those who suffer from anxiety disorders may become afraid that they will experience a fear response. They perceive their fear responses as negative and go out of their way to avoid those responses. Leading all to what I said, I believe that fear is mostly all emotion and you can control your fear somewhat and what you fear.
