Depression is the most common mental illness at present, characterized by persistent and long-term depression, and it is the main type of mental illness of modern people. Clinically, we can see that we are depressed, unhappy, depressed for a long time in reality, from depression at the beginning to heartbreak at the end, feeling inferior, miserable, pessimistic and world-weary, feeling that we are desperately torturing ourselves every day, being negative and escaping, and finally even having suicidal tendencies and behaviors. The patient has somatization symptoms. Chest tightness and shortness of breath. I just want to lie in bed every day and don't want to move anything. There is obvious anxiety. More serious people will have symptoms of schizophrenia such as auditory hallucination, paranoia and multiple personality. Each episode of depression lasts at least 2 weeks, 1 year, or even several years, and most cases have a recurrence trend.
