Post Traumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) are mental health conditions that can develop following exposure to traumatic events. These conditions affect how people think, feel and function after surviving or witnessing events that were frightening, threatening or overwhelming.
Trauma can result from a single incident or from prolonged and repeated exposure to distressing experiences. While not everyone who experiences trauma develops PTSD or CPTSD, for those who do, the effects can be significant. With the right support, recovery is possible.
PTSD can develop after a single traumatic event such as a car accident, assault, natural disaster, military combat or sudden loss. It is marked by:
CPTSD is a related condition that can develop after prolonged or repeated trauma, often during childhood or in settings where escape was not possible. Examples include ongoing abuse, domestic violence, exploitation or war. In addition to the symptoms of PTSD, CPTSD may involve:

These conditions arise when the brain and body remain in a state of threat long after the danger has passed. The trauma response is not just psychological—it affects the nervous system, memory processing, emotional regulation and sense of safety.
Risk factors include:
In Australia, PTSD affects around one in twenty people in any given year. It is more common in first responders, military personnel, refugees, survivors of abuse and people exposed to natural disasters or accidents.
Myth: Only soldiers or first responders develop PTSD
Truth: Anyone can develop PTSD or CPTSD after trauma. This includes survivors of accidents, abuse, illness or grief.
Myth: People with PTSD are dangerous or unstable
Truth: This stigma is harmful and untrue. Most people with PTSD are coping with internal distress and deserve compassion and support.
Myth: Trauma only affects people who are weak
Truth: PTSD and CPTSD have nothing to do with strength or weakness. They are human responses to overwhelming events.
Untreated PTSD or CPTSD can affect every area of life, including relationships, work, physical health and emotional wellbeing. However, evidence shows that timely, trauma-informed care leads to meaningful recovery.

Our services include:
Tina, 38, experienced childhood emotional abuse and multiple adult traumas. She struggled with nightmares, trust issues and a persistent sense of shame. With the support of a MeHelp psychologist trained in EMDR and trauma-informed care, Tina began to process her experiences, improve emotional regulation and slowly re-establish safe connections. She now describes herself as healing, rather than broken.

Can PTSD or CPTSD go away on its own? Some people recover with time and support, but for others, symptoms persist. Therapy is highly effective and can significantly improve quality of life.
Is therapy online effective for PTSD and CPTSD? Yes. Many people find online therapy helpful, particularly when it is structured and supported by trauma-informed clinicians.
Do I need a formal diagnosis to get help? No. If you are experiencing distress or symptoms that affect your daily life, you can access therapy whether or not you have a diagnosis.
Can childhood trauma cause CPTSD later in life? Yes. Repeated or chronic trauma in childhood is a common cause of CPTSD and often affects adult relationships, identity and emotional regulation.
Your trauma does not define you. With care, safety and evidence-based support, it is possible to move beyond survival and into healing. You are not alone.

There's rarely one single cause. Most of the time, post traumatic stress disorder (ptsd) and complex ptsd develops from a mix of life experiences, biology, and the environment a person grew up in. Stressful events, family history, and how someone learned to cope with big feelings as a child all play a part.
Understanding the "why" doesn't make the experience smaller — but it can take some of the self-blame out of it. What you're going through makes sense, given everything that came before it.
A psychologist can help you join the dots between what's happened in your life and what you're feeling now — and start to shift the patterns gently.
Watching someone you care about struggle with post traumatic stress disorder (ptsd) and complex ptsd is hard. You might feel helpless, worried, or unsure of what to say. That's normal.
You can help by:
If you're the one supporting them, you're allowed to seek your own therapy too — it doesn't take anything away from them.
The feelings below are common with post traumatic stress disorder (ptsd) and complex ptsd. They're not signs that something is wrong with you — they're signs of what you've been carrying.
Anxiety and feeling on edge. Always scanning for the next thing to go wrong. Hard to switch off.
Self-doubt. Second-guessing your decisions, memory, or read of the situation.
Low mood and tiredness. Tasks that used to feel easy take far more effort than they used to.
Shame. A sense that other people are coping better than you are. Shame eases in the right company.
Numbness or distance. Feeling foggy, disconnected, or like you're watching life from a step back.
Sleep changes. Trouble falling asleep, waking at 3am, or sleeping far more than usual.
You don't need a formal diagnosis to take what you're feeling seriously. The impact is real.
Healing from post traumatic stress disorder (ptsd) and complex ptsd is rarely a straight line. It moves in waves — clear one week, harder the next, then quieter again. That isn't a setback. That's the shape of healing.
Good therapy won't push you faster than you're ready to go. Pacing — not pressure — is how this work moves. Small, steady steps add up.
You might consider seeing a psychologist if you notice any of the following:

Works with the thoughts and behaviours keeping things stuck. Strong evidence across many conditions.
Helps you make room for hard feelings while still moving toward what matters to you.
EMDR, schema therapy, and IFS help process past experiences gently, without re-traumatising.
Builds the ability to notice what's going on inside without getting swept up in it.
