Self-abuse is not a technical term, it can possibly refer to a group of people who have a tendency to abuse themselves to achieve a kind of mental satisfaction by harming themselves, and can be seen in people with mental disorders. For example, schizophrenia and depression. How to treat self-mutilation depends first on what the patient’s symptoms are. If the patient is mainly emotionally self-abusive, for example, the patient tends to be very unconfident, devalues himself, thinks he is worthless, accomplishes nothing, and even blames himself, sins himself, has such thoughts or even behaviors of wanting to die or commit suicide, to be treated with medication. For example, antipsychotic drugs such as olanzapine, quetiapine, risperidone, etc., and antidepressants such as paroxetine and citalopram. In addition, psychological treatment is also available, mainly supportive psychotherapy to encourage, comfort, understand and support the patient, improve the patient’s self-esteem and self-confidence, and allow the patient to get to know and understand himself better and to exert his ability to solve the problems in his life. If the patient’s self-mutilating behavior is more in the form of hurting himself, such as causing physical breakage or even organ damage to himself, he should be hospitalized. Patients need to be monitored 24 hours a day to prevent self-injury and self-mutilation. It is also necessary to take such antipsychotic or antidepressant medications, as well as anti-anxiety medications, such as alprazolam and clonazepam. Psychotherapy is also needed to gradually reduce the patient’s self-harming and self-injurious behavior and to replace this psychologically satisfying behavior with a corrective one.
