Introduction
"Sunny depression" is not a formal medical term, but commonly refers to a state in which individuals conceal inner depression while outwardly appearing positive. Symptoms may include appearing optimistic on the surface while feeling down internally, hiding and suppressing emotions, significant fatigue from social interactions, tendencies toward self-criticism, and abnormalities in sleep or appetite. Patients often mask their suffering with a façade of happiness, making the condition easy to overlook. If emotional conflict and psychological exhaustion persist over time, timely medical consultation is recommended.

Sunshine depression is not a formal medical term, but commonly refers to a state in which individuals experience inner depression while outwardly pretending to be positive. Symptoms may include appearing optimistic on the surface while feeling down internally, hiding and suppressing emotions, significant social exhaustion, tendencies toward self-denial, and abnormalities in sleep and appetite. Patients often mask their suffering with apparent happiness, making the condition easily overlooked. If emotional conflict and internal exhaustion persist over time, prompt medical consultation is recommended.

1. Appearing optimistic while feeling low: The individual presents an outward image of positivity and cheerfulness, actively participates in social activities, and seeks to please others, yet experiences persistent low mood when alone, filled with helplessness and sadness—resulting in a stark emotional contrast.

2. Emotional concealment and suppression: There is a deliberate avoidance of expressing negative emotions; the person is unwilling to share their pain with others and bears stress and grievances alone. Prolonged suppression can lead to sudden emotional breakdowns.

3. Noticeable social fatigue: Maintaining a cheerful demeanor during social interactions requires considerable effort, leading to extreme exhaustion afterward. This may result in a tendency to avoid socializing altogether—despite a deep desire for solitude, there is also fear of loneliness.

4. Tendency toward self-negation: An excessive pursuit of perfection leads to harsh self-criticism. Individuals frequently fall into patterns of self-doubt and self-blame, believing their happiness is merely an act and feeling a profound lack of worth.

5. Sleep and appetite disturbances: These may manifest as insomnia, early morning awakening, or excessive sleeping. Appetite may be significantly reduced, leading to weight loss, or the individual may engage in binge eating to cope with emotions, resulting in abnormal weight gain.

In daily life, pay close attention to your true emotions, allow yourself to appropriately express negative feelings, and avoid overcompensating with false strength. Communicate openly with trusted individuals, engage in activities that help you relax, and maintain regular sleep patterns and a balanced diet.
