Depression and anxiety are different conditions, but they can often come together. Anxiety is an emotional response that is experienced when perceiving a stimulus as threatening; and allows the person to take actions to protect themselves and resolve stressful situations. However, being present for long periods and constantly, it loses its functionality. The person with depression may also experience intense feelings of anxiety, characterized by constant intense worry or fear, in the face of a potentially threatening stimulus. The anxious emotional response generates physical, affective, cognitive and behavioral symptoms. Anxiety is characterized by being anticipatory, it is directed towards the future and generates catastrophic scenarios in the mind; leading to the avoidance of situations, people or stimuli that provoke said emotional response.
