Lack of love depressive personality is considered to be the patient’s lack of love, i.e. lack of love from family, friends and partners around him/her, resulting in changes in emotional personality, which may manifest as sullenness, depression, etc. If the symptoms do not occur frequently and occasionally feel lonely or despondent, etc., no special treatment is needed and can be relieved by communicating with others and diverting attention. If depression occurs frequently and affects normal work and life, exogenous depression may occur due to lack of love. Changes in personality and performance mainly include: 1. Emotional symptoms: The more obvious symptoms are depressed mood, slow thinking, unresponsiveness, social impairment, etc. Thoughts are usually negative and pessimistic. When there is a lack of care from others, patients may also show low self-esteem and helplessness. 2. Psychological symptoms: Patients may have psychological symptoms, such as fear, dread, agitation, irritability, etc. Due to the lack of care from others, they may become more sensitive than before, and may even have delusions and hallucinations. 3. They can be easily confused with other physical symptoms. The performance of depressive personality due to lack of love varies from person to person because of individual differences. If the degree of depression is mild, it can usually be self-regulated. If the patient is more depressed, with a pessimistic and negative personality and extreme sensitivity, he/she should actively go to the hospital and seek help from a psychologist.
