Depression is a type of mental illness, and depression is more painful during an episode. In what ways is it painful? The main manifestations include insomnia, early awakening, diminished interest, not being interested in things you used to like, preferring to be alone, not communicating with outsiders, affecting normal work and life, as well as slow thinking, slower reaction, memory loss, and in more serious cases, the tendency or behavior of suicide or self-injury, all of which are the greater pains that depression can bring. Therefore, if you have related symptoms, it is recommended to go to the psychiatric psychology department of the hospital as soon as possible to get a clear diagnosis and clarify the degree of depression. Mild can take psychotherapy, cognitive-behavioral therapy or self-adjustment, and moderate depression or above may need antidepressant drugs, such as fluoxetine, paroxetine, etc., to help treat it.
