Anxiety is similar in nature to fear. In both cases, a reaction to danger is manifested, which is of greater value if the threat has a real danger. But there are also differences. Fear is always associated with a specific object or situation, and anxiety is a reaction to an imaginary, unknown threat and is always based on internal conflicts of the individual. Anxiety is caused not by the presence of danger, but by the lack of ability to avoid it if it appears. Each of us has experienced an anxious state at least once in our lives. This is normal in stressful situations and for most people it is a temporary condition. In some cases, anxiety becomes protracted, and in the worst case, continuous. Then it turns into a painful, persistent state, which may be accompanied by unpleasant physical sensations (tachycardia, reactions of the digestive tract, dry mouth, increased sweating, headaches, pain in the back of the head, skin irritations and much more). A wide range of physiological reactions due to anxiety explains , why prolonged anxiety causes psychosomatic disorders, and the state of anxiety itself is often “masked” by complaints of a somatic nature. Sometimes this condition goes away on its own, sometimes it worsens and becomes more and more difficult to bear, especially if life circumstances are unfavorable. When there is a constant threat to social status, financial well-being, etc., everything around seems potentially threatening. The worst case scenario is when anxiety develops into a phobia. Then psychoprotection plays a cruel joke and the experience of anxiety is replaced by fear, with a strong, inappropriate fear of actions/objects (for example, moths) or fear of fear when a dangerous situation has not yet arrived, but the person is already scared, scared that something terrible will happen .This happens because although experiencing fear is also unpleasant, it is at least clear what you are afraid of, and this would be amenable to at least some control, unlike anxiety. In conclusion, I would like to emphasize that fear of moderate strength is most often useful because it prepares a person to face real difficulties and dangers. Increased anxiety is dangerous because it weakens the condition and interferes with normal life, and in this case, it is better to consult a specialist.
