I feel fatigued all the time. I was prescribed antidepressant medications during childhood, but I have not taken any medicines for the past 15 years. What could be causing my constant tiredness, and what should I do?
Feeling tired all the time can happen due to many different reasons, and it is important to identify the exact cause rather than ignoring the symptoms. Constant fatigue may be related to poor sleep, stress, anxiety, lack of physical activity, unhealthy eating habits, vitamin deficiencies such as low Vitamin B12 or Vitamin D, anaemia, thyroid problems, diabetes, or mental health conditions such as Depression. Since you were prescribed antidepressant medicines in childhood, it is also possible that emotional or psychological factors may still be contributing to your tiredness, even if you have not taken medicines for many years. Sometimes depression or anxiety does not only cause sadness but can also lead to low energy, poor concentration, lack of motivation, body weakness, and disturbed sleep. To improve your condition, try to maintain a regular sleep schedule, eat balanced meals, drink enough water, and include light exercise such as walking, yoga, or stretching because regular physical activity can improve both energy and mood. Avoid excessive caffeine, smoking, alcohol, and irregular sleeping habits, as these can worsen fatigue over time. It is also important to reduce stress and take short breaks during work or study hours. Since your symptoms are persistent, it would be a good idea to consult a doctor for a proper check-up, including blood tests for anaemia, thyroid function, Vitamin B12, Vitamin D, and blood sugar levels. If emotional stress, low mood, anxiety, or loss of interest are also present, speaking with a mental health professional may help identify whether counseling, lifestyle changes, or treatment is needed. With proper evaluation and care, most causes of long-term fatigue can be managed effectively, and energy levels usually improve gradually over time.
