Anxiety manifests itself through physical and psychological symptoms. It is usually characterized by excessive concern about a future situation. You don't live the present well, always worried about the future. When controlled, it is the body's natural reaction to possible threats, which allows us to remain alert to any danger that may arise. However, it can be intense, prolonged and without an apparent cause. In these cases, people tend to isolate themselves and avoid any situations they consider dangerous, even when they are not.
