Depression and anxiety are two different concepts, but they often exist at the same time. Patients with anxiety are more susceptible to negative emotions because they are usually too worried, nervous and anxious, anxious and fearful; depressed patients are also prone to anxiety because they are often pessimistic and self-critical. Clinical differentiation is needed according to the order of appearance and the main symptoms exhibited.1. Depression: manifests as depressed mood. The core symptoms are depressed mood, such as feeling hard inside most of the time in daily life; diminished interest, loss or lack of interest in what they used to love to do; lack of pleasure, not being able to experience pleasure from daily life; slow thinking, reduced concentration, feeling pessimistic, self-blame, and even serious suicidal tendencies; 2. Anxiety: itself is a normal, adaptive way of facing crisis, manifested as worry fear, and dread. However, the core symptoms are excessive reaction in the face of crisis or continuous anxiety when there is no crisis, which can affect daily life, such as irritability, difficulty sleeping, increased alertness, inability to sit still, and even dizziness and headache, nausea and vomiting, chest tightness and shortness of breath, and other symptoms of autonomic disorders in severe cases. If you or your friends or family members experience anxiety or depression, you must go to a regular hospital for treatment in a timely manner. Early symptoms are mild and most can be relieved by psychological interventions and lifestyle changes. If you need to take medication, you may need to consider side effects carefully, and you need to take it under the guidance of your doctor strictly in accordance with medical advice, choose the right medication for you, and regularly review and adjust your medication, and do not stop it without authorization. Of course, regardless of anxiety or depression, you should receive formal psychotherapy and communicate with your doctor regularly and regularly to effectively reduce the relapse rate of anxiety and depression.
