Fear is a primary feeling that we all experience from time to time. What does it mean the primary feeling? It is a natural and necessary feeling that helps to make appropriate action in an emergency. When we are faced with a dangerous situation through fear, we reduce the danger by choosing the most appropriate fighting, escaping or freezing behavior. But such an adaptive feeling turns into a problem that needs to be solved in some cases.If you feel an expectation that it will not be a real danger, this expectation is a fear that has become somatized, and if it causes some behavior and makes your life difficult, this is a fear that has become a maladaptive fear or anxiety.I hope my information is important to you... @kaylinart
