What are the symptoms of anxiety and what can cause anxiety?

Many of us feel anxious when we have a stressful event or situation coming up, and we are worried about it. This feeling is temporary and usually goes away after the event or situation has ended. Anxiety is when that feeling of anxiousness does not go away and is long term. Find out more about the symptoms of anxiety and what can cause anxiety.

Learn about the signs and symptoms of anxiety and what can cause anxiety so that you can get the support you need.



What is anxiety?

It is normal to feel anxious every now and then. If you feel jittery or nervous before public speaking, going on a date, dinner with the in-laws, or attending a job interview – that’s quite normal. Many people get ‘butterflies’ in their stomach before doing something that is stressful. These feelings are usually short-lived and go away once the event is over.

Anxiety is when those negative feelings last for a long time. The constant worry either doesn’t go away or you start to feel it for seemingly no specific reason.

You might find that these anxious feelings happen so often, or are so intense, that they affect your day-to-day life. Having anxiety may start to strain your relationships and your health.


Types of anxiety disorders

Anxiety is one of the most common mental health conditions in Australia. According to the latest mental health data from the Australian Bureau of Statistics, 2.3m Australians had an anxiety-related condition during 2017-18[1].

A person who has severe anxiety can be diagnosed with an anxiety disorder by a health professional. There are different types of anxiety disorders and a person can have more than one. Below are some of the more common anxiety disorders in Australia:

  • Generalised anxiety disorder
  • Post-traumatic stress disorder
  • Obsessive compulsive disorder
  • Social phobia
  • Agoraphobia
  • Panic disorder


“It’s normal to feel worried about stressful situations. However, if the anxiety stays with you after the situation or event has passed, it can start to affect your day-to-day life.”


Symptoms of anxiety

Anxiety symptoms may not be the same for everyone, and it may also depend on the type of anxiety you are experiencing.

If you have anxiety symptoms, you may start to think that you can’t handle your feelings or that things are not going your way. Remember that anxiety can be treated and there is help available. You can speak to your GP, a health professional or call 1300 651 251 to speak to a SuicideLine Victoria counsellor.


Causes of anxiety

Anxiety can be caused by a number of risk factors – there is usually a combination of things in a person’s life that can lead to anxiety. It can be caused by a stressful or traumatic event, your family history of mental health, or by physical health problems you are experiencing. We have compiled some of the common risk factors that can cause anxiety.


Common causes of anxiety – stressful situations

  • Stressful time at work
  • Changing jobs
  • Losing your job
  • Financial worries
  • Relationship problems
  • A major life event (e.g. having a new baby, moving to a new city)


Common causes of anxiety – traumatic events

  • Grieving the loss of a loved one
  • Experiencing coercive control
  • Experiencing abuse (verbal, emotional, physical or sexual)
  • Experiencing a traumatic event
  • Witnessing a traumatic event


Common causes of anxiety – mental health

Anxiety can develop when you have another mental health illness, for example, you may have depression and anxiety at the same time. A history of anxiety in your family may also contribute to it (but this doesn’t mean that you will develop anxiety).


Commons causes of anxiety – physical health

Living with a chronic illness (e.g. diabetes, heart disease, asthma) and managing the impact on your daily life can lead to having anxiety symptoms.


Getting help for anxiety

Anxiety can be complex, and sometimes you won’t be able to identify the cause of your anxiety, but you can get help. If you have symptoms of anxiety, don’t leave it untreated, as this may cause your anxiety to worsen over time. You can make an appointment with your GP who can make a mental health assessment, create a mental health treatment plan, and provide a referral to see a psychologist. If you already have a counsellor, psychologist or psychiatrist, speak to them about your anxiety and be honest with how you are coping.

Depending on the severity of your anxiety, there are some self-help strategies you can do to help manage your anxiety. These include positive self-talk, eating healthy foods, regular exercise, mindfulness relaxation and breathing exercises, meditation, yoga, and avoiding alcohol.


SuicideLine Victoria counsellors can also help you work through your anxiety. Call us on 1300 651 251 or click the floating chat button on the right to chat with a counsellor online. You do not need a referral to use our service.
