Anxiety: When Worry Becomes a Problem

How to recognise anxiety, understand what keeps it going and know when to seek help

Worry is part of normal life.

It can help you prepare for a difficult conversation, notice danger or solve a problem before it becomes worse. Anxiety can also sharpen attention when something important is at stake.

The problem begins when worry becomes persistent, difficult to control or out of proportion to the situation. It may start affecting sleep, concentration, relationships, work or the things you are willing to do.

Anxiety is not a sign of weakness. It is a common and treatable health problem.

What is anxiety?

Anxiety is the body and mind’s response to perceived threat or uncertainty.

When your brain believes something may be unsafe, your nervous system prepares you to respond. Your heart may beat faster, your breathing may change and your muscles may tense. Your attention shifts towards possible danger.

This response can be useful when there is a genuine threat.

With an anxiety condition, the alarm response may activate too often, remain active after the threat has passed or respond strongly to situations that are uncomfortable but not actually dangerous.

Anxiety conditions are among the most common mental-health problems in Australia and can have a significant effect on daily life.

When does ordinary worry become a problem?

Normal worry is usually linked to a particular concern and settles when the issue is resolved.

Worry may be becoming excessive when it is:

• Present on most days
• Difficult to control
• Out of proportion to the likely risk
• Moving constantly from one topic to another
• Causing repeated reassurance-seeking
• Leading you to avoid people, places or activities
• Interfering with sleep, work or relationships
• Causing significant distress

Excessive worry may focus on health, finances, family, work, safety or everyday decisions. The subject can change, while the pattern of worrying remains.

You do not need to wait until anxiety becomes severe before seeking help.

What anxiety can feel like

Anxiety can affect thoughts, emotions, behaviour and the body.

Thoughts and emotions
You may experience:

• Repeated “what if?” thoughts
• Expecting the worst
• Difficulty tolerating uncertainty
• Racing thoughts
• Poor concentration
• Irritability
• Feeling tense, restless or on edge
• A sense of dread or impending danger
• Feeling unable to switch off

Physical symptoms
Anxiety may cause:

• A racing or pounding heartbeat
• Fast or shallow breathing
• Sweating
• Shaking
• Nausea or stomach discomfort
• Dizziness
• Tightness in the chest
• Muscle tension
• Headaches
• Difficulty sleeping
• Fatigue

These symptoms can feel frightening. They may also occur with medical conditions, so new, severe or unexplained symptoms should not automatically be assumed to be anxiety.

Anxiety can take different forms

Anxiety is not one single condition.

Generalised anxiety
This involves persistent and difficult-to-control worry across several areas of life, often accompanied by tension, irritability, poor sleep and fatigue.

Panic attacks and panic disorder
A panic attack is a sudden surge of intense fear or discomfort. Symptoms may include a racing heart, breathlessness, shaking, chest discomfort, dizziness or fear of losing control.

Some people then become anxious about having another attack and begin avoiding situations where escape or help might feel difficult.

Social anxiety
Social anxiety involves marked fear of embarrassment, scrutiny or negative judgement in social or performance situations. Avoidance can gradually interfere with relationships, education and work.

Specific phobias
A person may experience intense fear of a particular object or situation, such as flying, needles, animals or enclosed spaces.

Other conditions, including obsessive-compulsive disorder and post-traumatic stress disorder, can also involve significant anxiety but require their own assessment and treatment approach.

Why anxiety can keep itself going

Anxiety often continues through a cycle.

A situation triggers a threatening thought. The thought produces physical anxiety. You then avoid the situation, seek reassurance or perform a safety behaviour. This reduces anxiety briefly, but your brain never learns that you may have coped safely.

For example:

1. You notice a physical sensation.
2. You interpret it as something dangerous.
3. Anxiety increases the sensation.
4. You repeatedly check, search online or seek reassurance.
5. Relief lasts briefly.
6. The next sensation feels even more threatening.

Avoidance is understandable, but repeated avoidance can make anxiety stronger over time.

What can help in the moment?

When anxiety is high, begin by helping your body settle.

Slow the breathing
Try breathing gently rather than taking very large breaths.

A simple pattern is:

• Breathe in comfortably for about three seconds
• Breathe out slowly for about five or six seconds
• Continue for one or two minutes

The aim is not to force the anxiety away. It is to reduce over-breathing and give your nervous system time to settle.

Ground your attention
Name:

• Five things you can see
• Four things you can feel
• Three things you can hear
• Two things you can smell
• One thing you can taste

This can shift attention away from catastrophic thoughts and back to the present.

Label what is happening
Try saying: “This feels uncomfortable, but it may be anxiety rather than danger.”

This does not dismiss genuine symptoms. It creates a small pause before automatically assuming the worst.

Challenge worry rather than arguing with every thought

An anxious thought is not the same as a fact.

Ask yourself:

• What evidence supports this fear?
• What evidence does not support it?
• Am I treating a possibility as a certainty?
• What would I say to someone I care about?
• Is there a useful action I can take?
• If there is no action, can I postpone the worry?

Setting aside a brief daily “worry time”, writing concerns down and asking whether the worry is realistic or useful can help prevent worry from dominating the entire day.

Gradually reduce avoidance

Avoidance often provides immediate relief but reinforces anxiety.

A more helpful approach is usually gradual exposure: facing a feared but reasonably safe situation in manageable steps and remaining there long enough to learn that anxiety can rise and then fall.

For someone with social anxiety, this might progress from:

• Making brief eye contact
• Asking a simple question
• Joining a short conversation
• Attending a small social event
• Speaking in a larger group

Exposure should be planned and proportionate. Complex trauma, severe panic or significant medical concerns may require professional guidance.

Protect the foundations

Lifestyle changes alone do not treat every anxiety disorder, but they can support recovery.

Helpful foundations include:

• Regular physical activity
• Adequate sleep
• Regular meals
• Reducing excessive caffeine
• Limiting alcohol and other drugs
• Spending time outdoors
• Maintaining social connection
• Making time for enjoyable activities

Caffeine, nicotine and some stimulant medicines can worsen physical anxiety symptoms in susceptible people. Alcohol may reduce anxiety briefly but often worsens sleep and next-day anxiety.

Psychological treatment

Psychological therapy is an effective treatment for anxiety.

Cognitive behavioural therapy, commonly called CBT, helps people:

• Understand the anxiety cycle
• Identify unhelpful thinking patterns
• Reduce avoidance
• Practise gradual exposure
• Build problem-solving and coping skills

CBT may be delivered face to face, by telehealth or through structured online programs.

Your GP can discuss whether a mental health treatment plan may help with access to a psychologist or another mental-health professional.

When medicines may help

Not everyone with anxiety needs medicine.

For moderate or severe anxiety, persistent symptoms or significant impairment, a GP may recommend an antidepressant medicine, often an SSRI or SNRI. These medicines can take several weeks to have their full effect.

Benzodiazepines can reduce anxiety quickly but are generally reserved for short-term use because they may cause sedation, impaired driving, tolerance and dependence.

Do not stop an antidepressant or benzodiazepine suddenly without medical advice.

When to see your GP

Arrange an appointment when anxiety:

• Affects your life on most days
• Is difficult to control
• Causes significant distress
• Leads you to avoid important activities
• Interferes with sleep, relationships or work
• Causes frequent panic attacks
• Leads to repeated medical checking or reassurance
• Occurs alongside low mood or harmful substance use
• Does not improve with reasonable self-care

Your GP may ask about your symptoms, medical history, medicines, caffeine, alcohol and other factors. They may also consider physical conditions that can mimic or worsen anxiety.

Early help can prevent the pattern becoming more entrenched.

When to seek urgent help

Call 000 if you or someone else is in immediate danger, or if symptoms may indicate a medical emergency.

Seek urgent support if anxiety is accompanied by:

• Thoughts of suicide or self-harm
• Inability to keep yourself safe
• Severe agitation or confusion
• New severe chest pain
• Collapse
• Sudden severe breathlessness
• New weakness, speech difficulty or other neurological symptoms

For crisis support, call Lifeline on 13 11 14.

For help finding appropriate Australian mental-health services, call Medicare Mental Health on 1800 595 212. Healthdirect also provides 24-hour nurse advice on 1800 022 222.

Start with one change

Choose one practical first step:

• Write down what you are worrying about
• Reduce one source of excessive caffeine
• Practise slow breathing for two minutes
• Take a short walk
• Delay reassurance-seeking for ten minutes
• Face one small, safe situation you usually avoid
• Book a longer GP appointment to discuss anxiety

The aim is not to eliminate every anxious feeling. It is to stop anxiety from controlling your choices.

The bottom line

Anxiety becomes a problem when worry is persistent, difficult to control, distressing or begins limiting your life.

Physical symptoms can be intense, but avoidance and repeated reassurance often keep the cycle going. Breathing techniques, regular movement, better sleep, reducing stimulants and gradually facing safe situations can help.

Persistent anxiety deserves proper treatment. Psychological therapy — particularly CBT — is effective, and medicines may help some people.

You do not need to wait until anxiety is overwhelming before asking for support.
