Anxiety: what is it and when should you seek help?
Anxiety is the most common mental health concern in Australia, affecting around one in four people at some point in their lives. But anxiety is also widely misunderstood. This article explains what anxiety actually is, how it shows up differently for different people, and when it's worth seeking support.
What is anxiety?
Anxiety is a natural human response to perceived threat or uncertainty. At its core, it is the body's alarm system — designed to prepare us to respond to danger by triggering the 'fight, flight, or freeze' response. In short bursts, anxiety can be useful: it sharpens focus, motivates action, and keeps us alert in genuinely risky situations.
The difficulty arises when the alarm system becomes overactive — firing in situations that are not genuinely dangerous, or staying switched on long after a threat has passed. When anxiety is persistent, disproportionate to the situation, or begins to interfere with daily life, it has moved beyond a normal stress response into something that warrants attention.
How anxiety shows up
Anxiety manifests differently from person to person, and can affect the body, thoughts, and behaviour simultaneously. Physical symptoms can include a racing heart, shortness of breath, muscle tension, nausea, dizziness, and fatigue. Many people experience anxiety primarily as physical sensations and do not immediately recognise it as anxiety at all.
Cognitively, anxiety often involves persistent worry, catastrophic thinking, difficulty concentrating, and a tendency to overestimate threat while underestimating one's ability to cope. Behaviourally, anxiety commonly leads to avoidance — steering clear of situations, people, or activities that trigger anxious feelings. While avoidance provides short-term relief, it reinforces anxiety over time and gradually narrows the life a person feels able to live.
Types of anxiety disorders
Anxiety is not a single condition. The term covers a range of distinct disorders, each with its own pattern of symptoms. Generalised Anxiety Disorder (GAD) involves persistent, wide-ranging worry about everyday matters. Social anxiety disorder centres on fear of judgement or humiliation in social situations. Panic disorder involves recurrent, unexpected panic attacks and fear of future attacks. Specific phobias involve intense fear of particular objects or situations.
Health anxiety, separation anxiety, and agoraphobia are also recognised anxiety disorders. Many people experience symptoms that span more than one category, and anxiety frequently co-occurs with depression. Regardless of the specific presentation, effective psychological treatments are available for all anxiety disorders.
Evidence-based treatments for anxiety
Cognitive Behavioural Therapy (CBT) is the most extensively researched psychological treatment for anxiety and has a strong evidence base across all anxiety disorders. CBT works by identifying and challenging the unhelpful thought patterns and avoidance behaviours that maintain anxiety, and gradually building tolerance for uncertainty and discomfort.
Acceptance and Commitment Therapy (ACT) is another well-supported approach that focuses on building psychological flexibility — learning to relate differently to anxious thoughts and feelings rather than fighting them, and moving towards a life guided by values rather than avoidance. For anxiety rooted in past trauma, EMDR may also be an appropriate part of treatment.
When is it time to seek support?
It can be difficult to know when anxiety has crossed the line from normal stress into something that needs professional attention. A useful guide is impact: if anxiety is regularly interfering with your work, relationships, sleep, or ability to do things that matter to you, it is worth speaking with a psychologist.
You do not need to be in crisis to seek support, and you do not need to have a diagnosed anxiety disorder. Many people find that even a few sessions with a psychologist provide meaningful relief and equip them with skills they use for the rest of their lives. If you have been managing anxiety on your own for a long time and feel stuck, reaching out is a reasonable and worthwhile step.
