May 25th is the National Day for Mental Health of College Students. In recent years, the mental health of college students has become a hot topic of discussion. How do college students determine whether they have mental illness? What can I do if I suspect I have a mental illness? How should universities protect the mental health of college students? What is the mental health status of college students? Not long ago, the Institute of Psychology of the Chinese Academy of Sciences and the Social Sciences Academic Press jointly released the Survey Report on College Students' Mental Health in 2022. The survey results show that the overall mental health status of contemporary college students is good. The report indicates that 21.48% of college students may be at risk of depression, and 45.28% of college students may be at risk of anxiety. At the same time, the report also revealed that students from key universities have a higher risk of depression and anxiety than students from non key universities; The risk of depression and anxiety among undergraduate students is significantly higher than that of vocational students. Tan Jianfeng, Vice Dean of the School of Humanities and Management at Guangdong Medical University, Director of the Center for Mental Health Education and Consultation, PhD in Psychology, and Associate Professor of Psychology, introduced to the Yangcheng Evening News reporter that the most common mental illnesses among college students are depression, anxiety, and bipolar disorder. Among them, the incidence rate of bipolar affective disorder has increased in recent years. Compared with depression and anxiety, bipolar affective disorder is more complex in its treatment and easier to be ignored by people around. Universities and the whole society should raise awareness of bipolar disorder, "said Tan Jianfeng. Hollow disease "is also a new concept that has emerged in recent years. The so-called hollow disease refers to the lack of motivation for students to learn, pursuit of life, and interest in anything, and even the decreasing communication and contact with others. Tan Jianfeng pointed out that some college students do not understand the scale of "combining work and rest" and blindly pursue comfort and enjoyment. Under the influence of multiple factors, the trend of hollow heart disease among college students has become increasingly evident. How to determine if you have a mental illness? Many students experience emotions such as sadness when experiencing setbacks, and in severe cases, it can even affect their lives. So, how do college students correctly determine whether they are in a bad mood or have psychological illnesses? Tan Jianfeng stated that cognition, emotion, and will are the three basic subjective psychological activities of a person, which are the three dimensions for evaluating a person's mental health. Cognition is mainly about the understanding of "how", emotion is mainly about the understanding of "how", and will is mainly about the understanding of "how". We need to compare vertically (compared to our past self), horizontally (compared to people around us, compared to public standards), and judge whether our own situation matches the real environment from these three aspects. If there are significant differences or mismatches in the three levels, it is necessary to consider the possibility of mental illness or mental illness. "Tan Jianfeng said that if students are immersed in emotions for one or even three months after experiencing a certain trauma, it may belong to the stage of" psychological problems "; If it exceeds 6 months and affects normal life and interpersonal communication, it may have developed to the level of "psychological disorder". If it develops into a psychological illness, timely treatment is necessary, "Tan Jianfeng emphasized. How to Protect Universities
