Root of the fear (in fact for anything) is the corresponding belief you are holding. Based on the belief you start behaving certain way. So, if you must eliminate the belief then what you do? If you have enough self-awareness on your thoughts and behaviors, then probably you can change it by yourself. But that is not that easy mainly because most people are not self-aware about the dis empowering/negative belief they are holding on. Even if they are aware about these it is difficult to eliminate them as these beliefs might have rooted during the childhood times. This is where CBT helps significantly. Unfortunately, in many societies people hesitate to see psychologist because they think that others might see them as weak or some problematic. And they continue to live their life carrying the same old beliefs and curse on the planets and destiny. Good news is now a days more awareness is coming on taking help from psychologists. CBT is very powerful and effective to remove any blocks provided you get a good psychologist.
