It’s normal to feel sad from time to time, especially in response to life’s challenges, but depression is more than just occasional sadness. If you find that your low mood persists for weeks, or you’re experiencing other symptoms such as changes in sleep, appetite or energy levels, it may be depression. Sadness often has a clear cause and generally eases with time, whereas depression can feel overwhelming and unshakable, even without a specific trigger. Remember, it’s always okay to seek professional guidance if you’re unsure: getting help early can make a significant difference.
