Premarital depression is a condition in which the patient suffers from depression due to anxiety about people and events related to marriage, and usually occurs in the premarital period. One of the causes of premarital depression is related to the personality characteristics of the patient, such as being introverted, withdrawn, and uncommunicative, and may also be passive and unassertive, and may also be related to excessive stress; another may be related to adverse stressful events such as disagreement between the two parties. Patients may be sullen, unconcerned about getting married or not confident enough, worried and afraid of not being able to handle the marriage, or they may easily lose their temper, sulk, often be alone or cry a lot. It is recommended to go to the psychology department or psychiatric department of a regular hospital for formal diagnosis and treatment as soon as possible.
