Which type of mental illness is characterized by depression and anxiety?

Neurosis is the term that encompasses a range of mental health issues characterized by anxiety, depression, and other emotional disturbances without a loss of touch with reality. Individuals experiencing neurosis may exhibit symptoms such as stress, anxiety, obsessive thoughts, and depression, which are often rooted in their emotional state rather than a severe psychological disorder. This differentiates neurosis from psychosis, which involves a disconnection from reality, and conditions such as schizophrenia and delusional disorder, which primarily feature more severe symptoms, including hallucinations and delusions. Therefore, the key characteristics of neurosis align directly with the presence of both depression and anxiety, making it the appropriate classification for the question posed.
