Generally, the onset of mental illness does not happen suddenly. If there are any related abnormal symptoms, it is advisable to seek medical attention promptly. The detailed explanation is as follows:

The development of mental illness results from the long-term accumulation of multiple factors, rather than an abrupt occurrence. Genetic predispositions may create a certain vulnerability, while abnormalities in brain neurotransmitter secretion can affect emotional and cognitive regulation. Prolonged exposure to significant stress, traumatic experiences, or living in isolation and oppressive environments continuously depletes psychological resilience. Additionally, unhealthy lifestyle habits and the impact of chronic diseases gradually weaken the body's and mind's adaptive capacity. When these factors accumulate beyond an individual’s ability to cope, they may trigger psychiatric disorders.

Maintaining regular sleep patterns and a balanced diet provides stable support for both physical and mental health. Frequent communication with family and friends helps release inner stress and prevents prolonged buildup of negative emotions. Actively engaging in mild exercise and enjoyable activities enriches one’s inner world. If emotional or behavioral abnormalities arise and persist without improvement, timely professional help should be sought. Showing adequate understanding and self-compassion strengthens the defenses of mental well-being.
