Suddenly feeling very tired and overwhelmed, what should I do?

Generally, sudden feelings of extreme fatigue and emotional oppression may be caused by overexertion, inadequate nutrition, emotional stress response, adjustment disorders, or mild depressive episodes. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms through lifestyle adjustments, medication, and other treatments under a doctor's guidance. Specific analyses are as follows:

1. Overexertion: Long-term sleep deprivation or high-intensity work leads to continuous physical and mental exhaustion, resulting in fatigue and low mood. Immediately pause current tasks, ensure 7–8 hours of sleep per night, soak feet in 40°C warm water for 15 minutes before bedtime, avoid using mobile phones before sleeping, and take a 10-minute break after every hour of work.

2. Inadequate Nutritional Supply: Irregular eating habits can lead to deficiencies in carbohydrates and B vitamins, affecting energy levels and nervous system regulation. Timely consume foods such as whole wheat bread and eggs, maintain regular meals, and take supplements like vitamin B complex tablets, oryzanol tablets, and mecobalamin tablets as directed by a physician.

3. Emotional Stress Response: Sudden events such as job loss or the death of a loved one may trigger short-term emotional breakdowns and physical discomfort. Share your feelings with trusted individuals, release emotions through activities like running or shouting, and use medications such as Jieyu Anshen Granules, Shugan Jieyu Capsules, or Xiaoyao Pills under medical supervision.

4. Adjustment Disorder: Environmental changes such as changing jobs or moving homes may overwhelm psychological adaptation, leading to persistent fatigue and depression. Actively familiarize yourself with the new environment, participate in social activities to build new connections, receive psychological counseling, and take medications such as sertraline hydrochloride tablets, escitalopram oxalate tablets, or citalopram hydrobromide tablets as prescribed.

5. Mild Depressive Episode: Characterized by persistent low mood, reduced interest, and severe lack of energy. In addition to psychotherapy, engage in 30 minutes of aerobic exercise daily and take medications such as paroxetine hydrochloride tablets, venlafaxine extended-release tablets, or mirtazapine tablets as directed by a doctor.

In daily life, avoid consuming coffee and strong tea. Increase intake of nutrient-rich foods such as bananas and spinach. Family members should offer companionship and attentive listening, avoid criticism, and support comprehensive interventions to gradually relieve physical and mental distress and restore well-being.
