Background - Why did we choose to tackle negative emotions?
Depression is a long-term mental health condition causing uncontrollable negative emotions, sleep disturbances, physical problems, and even thoughts of death. Severe depression is not only a personal problem but also has significant impacts on interpersonal relationships and society.
According to a global investigation launched by the World Health Organization (WHO) in 2023, 2.8 million people are suffering from depression worldwide, and the number of people with depression grows year by year (World Health Organization, 2023). Similarly, a survey conducted by the American Institute of Public Opinion indicated that more and more people are experiencing negative emotions, as shown in Figure 1 (Gallup, 2023). According to their report, the percentage of the global population experiencing negative emotions rose 9% from 2006 to 2022.
