What You Should Know About Depression: Diagnosis, Symptoms, and Support

If you've been feeling persistently low, withdrawn, or emotionally exhausted, you may be wondering: Is this depression? While it's normal to feel down from time to time, depression is more than sadness—it’s a clinical condition that affects how you think, feel, and function.

Understanding a depression diagnosis can be the first step toward getting the support you need.


What Is Depression?

Depression, or major depressive disorder, is a common and serious mental health condition that affects millions of Australians each year. It's characterised by a persistently low mood and loss of interest in activities once enjoyed.

According to Beyond Blue, symptoms must last at least two weeks and cause significant distress or impairment to be diagnosed.

Common types include:

  • Major Depression

  • Persistent Depressive Disorder (Dysthymia)

  • Postnatal Depression

  • Seasonal Affective Disorder

How Depression Affects the Body and Mind

Depression doesn't just affect mood—it can impact your entire body.

Emotional and cognitive symptoms:

  • Ongoing sadness, hopelessness, or emptiness

  • Loss of interest or pleasure in activities

  • Difficulty concentrating or making decisions

  • Feelings of guilt or worthlessness

Physical symptoms:

  • Changes in sleep (insomnia or oversleeping)

  • Fatigue or low energy

  • Appetite or weight changes

  • Headaches, aches, or digestive issues

According to the Australian Institute of Health and Welfare, depression is one of the top causes of non-fatal disease burden in Australia.

How Can a Psychologist Help with Depression?

A psychologist can help you explore what’s contributing to your low mood, develop practical coping strategies, and guide you through evidence-based treatments.

Ways a psychologist can support you:

  • Diagnosis & assessment: Helping determine whether your symptoms meet clinical criteria

  • Therapy: Evidence-based therapies such as CBT and behavioural activation are shown to reduce depressive symptoms

  • Skill building: Learn tools to manage negative thought patterns and improve motivation

  • Support: Offering a safe, non-judgemental space to talk things through and feel heard

In some cases, psychologists work alongside GPs or psychiatrists if medication or further investigation is needed.

When Should I Seek Help?

If your mood has been low for more than two weeks, or if it’s affecting your relationships, work, or daily life, it’s time to reach out.

You don’t have to wait until things get worse. Early support makes a difference.
