What is neurosis?
Generally, neurosis refers to a type of mental disorder commonly characterized by symptoms such as anxiety, fear, and obsessive behaviors, but without loss of reality perception. A detailed explanation is as follows:

Neurosis is an umbrella term for a group of mental disorders primarily manifested by persistent psychological conflicts. Patients are aware of these conflicts and experience distress as a result, yet are unable to resolve them independently. Symptoms often include anxiety, fear, obsession, hypochondria, and others. Physically, patients may experience dizziness, chest tightness, insomnia, gastrointestinal discomfort, and similar symptoms; however, medical examinations reveal no clear organic abnormalities. These symptoms can affect emotional well-being and quality of life, but do not lead to significant cognitive or behavioral disturbances. Patients typically maintain clear insight into their condition and are willing to seek treatment.
In daily life, it's important to foster a relaxed psychological environment and avoid excessive focus on symptoms that may exacerbate discomfort. Help establish regular routines, including consistent sleep and wake times, and avoid exposure to stimulating content before bedtime. Encourage participation in relaxing activities such as walking or yoga to alleviate anxiety. Maintain a light and balanced diet, reducing intake of stimulants like coffee and strong tea. Patiently listen to the individual's inner feelings, provide emotional support, and guide them toward a rational understanding of physical responses. If symptoms worsen, promptly accompany them in seeking professional medical assistance.
