What are the manifestations of mental unhealthy?

Unhealthy psychology is very different from healthy psychology, which means that people can't adapt to the current and developing social environment with a positive, balanced and normal psychological state, and can't correctly analyze, understand and treat certain things. When they encounter difficulties or setbacks contrary to their wishes, they will have unpleasant psychological feelings and negative emotions, which are manifested as depression, sadness, resentment, or panic and disorientation.
