Everyone feels down sometimes. Depression is different: it’s a persistent, whole-body condition that affects how you feel, think, and function — and it’s both common and treatable. Recognising the symptoms is the first step toward getting help.
More than sadness
Ordinary sadness lifts. Depression settles in and stays, usually for at least two weeks, and it colours much more than mood. It’s a medical condition, not a weakness or something you can simply “snap out of” — and importantly, it responds well to treatment.
Emotional symptoms
- Persistent low, empty or flat mood
- Loss of interest or pleasure in things you used to enjoy (this is called anhedonia and is a core feature)
- Feelings of worthlessness, guilt or hopelessness
- Irritability or frustration, sometimes over small things
- A sense of numbness or disconnection
Physical symptoms
- Fatigue and low energy, even after rest
- Sleep changes — insomnia, or sleeping much more than usual
- Appetite or weight changes in either direction
- Slowed movements and speech, or restlessness
- Unexplained aches, pains or digestive problems
Cognitive symptoms
- Difficulty concentrating, remembering or making decisions
- A mind that dwells on the negative
- Thoughts that life isn’t worth living, or of harming yourself

When to seek help
If several of these symptoms have lasted two weeks or more and are affecting your daily life, it’s worth speaking to a professional. Depression is highly treatable, and earlier help usually means an easier recovery. A good starting point is our free, confidential depression self-check (PHQ-9) — it can’t diagnose you, but it helps you gauge severity and decide whether to reach out.
From there, your GP can discuss options, and for more complex or persistent depression a psychiatrist can provide specialist assessment and treatment. Read more about the depression care we provide and depression treatment options in Australia.
