People who have depression are advised to go to the psychiatric department, or psychology department, of a regular hospital for treatment. This is because the depressed mood of depression affects a person’s self-functioning, which means that the patient’s ability to regulate his or her emotions, control his or her impulses, and analyze, judge, and solve problems will be affected. If patients rely on themselves to alleviate their depression, it is difficult and may also cause delays. Patients with mild depression can start with psychotherapy or psychological counseling, while those with moderate to severe depression need medication. These are mainly antidepressants and small doses of antipsychotic drugs, or mood stabilizers, which should be diagnosed and treated by a psychiatrist in a regular hospital.
