This year's "Double 11" is the same as in previous years. Many people have started shopping and hoarding modes early on, but if you can't control your crazy shopping, you should be careful. Recently, female white-collar worker Xiao Xu couldn't control herself and was willing to overdraw credit cards, loans, etc. She bought many things but couldn't use them at all, and her temper became increasingly irritable. My family felt something was wrong and only after taking her to the doctor did they realize that she had bipolar disorder, which was the cause of her crazy shopping. Xiaoxu's "Double 11" this year belongs to the super long version, and she has been heavily overdrawn online shopping since October. At first, her family was completely unaware of her behavior, until they received a credit card bill and saw an overdraft of over 100000 yuan. The family was surprised, but it was too late to repent. This may seem outrageous, but it is not uncommon. Similar news occurs every year after the Double 11. Except for extreme cases, irrational online shopping that did not cause financial crisis in households is more common. Bipolar disorder generally refers to a mood disorder that includes both manic or hypomanic episodes and depressive episodes in clinical practice. Patients with bipolar disorder experience emotions like riding a roller coaster, sometimes excited and sometimes depressed. During manic episodes, patients are excited, talkative, restless, irritable, particularly energetic, feel particularly capable, and have increased activity; But during the onset of depression, one often feels depressed, feels hopeless in life, sleeps too much, has a strong sense of self disgust, decreases activity, and produces negative thoughts. Bipolar disorder is a mental illness that can lead to shopping addiction and even become a 'shopping frenzy'. Patients have a pathological possessive desire when faced with a wide range of goods, even if they know they are useless or repeat purchases, they will place orders without thinking, and even become overwhelmed if they don't buy a few things in a day. At present, mental diseases are frequently occurring, and the incidence rate of this disease will naturally rise. In the future, similar crazy overdraft online shopping phenomenon may become more and more common. Someone at home is crazy about overdrafting online shopping, which can quickly put the family into financial difficulties. Even a 'shopping maniac' may feel very regretful after waking up afterwards. Crazy online shopping poses great harm to families, and family members should supervise their loved ones who have this tendency and promptly take them to seek medical treatment and medication, especially during special periods such as the "Double 11". Patients with mental illness do not have the capacity for civil liability during the onset period, and they make a large number of pathological online purchases during this period. It is worth exploring whether it is possible to "return due to illness". Of course, "returning goods due to illness" involves various things, especially in the market order, which is difficult to avoid. Merchants have no way to verify whether the shoppers have mental illness and are in the onset stage. It is not easy to balance the rights and interests of all parties in "returning goods due to illness". In addition, they may not have the capacity for civil liability during online shopping, so theoretically, the guardian has the right to represent their shopping behavior and handle civil disputes caused by online shopping on their behalf. In that case, it is worth exploring whether the guardian can apply to the online shopping platform in advance to limit the online shopping behavior of the ward during the outbreak. Although it is necessary to launch such preventive measures, they also involve patient privacy, in order to
