Sadness is a normal reaction to loss, disappointment or stress. It usually eases within days and does not stop you from functioning. Depression is different: it lasts, it spreads into every part of life, and it does not lift just because something good happens.
The two-week rule
Doctors look for low mood or loss of interest on most days for at least two weeks, along with several of the following:
- Sleep problems — too little or too much
- Tiredness, slowed thinking, poor concentration
- Appetite or weight change
- Guilt, feeling worthless or hopeless
- Thoughts that life is not worth living
Why people delay
Many people think they should 'be strong' or that medicines are addictive. In reality, depression is a medical condition, and antidepressants are not habit-forming. Early treatment shortens suffering and protects work, studies and relationships.

Frequently asked questions
How long does depression treatment take?
Many people start feeling better within 4–8 weeks of starting treatment. Treatment usually continues for some months after recovery to prevent relapse.
Is depression a sign of weakness?
No. It is a medical condition linked to brain chemistry, stress and life events — not a character flaw.
