Complex PTSD vs PTSD: What's the Difference?

Updated: Nov 13

Most people have heard of PTSD. They picture a soldier coming home from war, or someone who survived a car crash and now can't drive. That picture is real, but it's only part of the story.
A lot of the people we work with didn't go through one terrible event. They went through something that lasted. A childhood that never felt safe. Years in a controlling or violent relationship. Growing up around addiction, neglect or constant criticism. They often don't think of themselves as "traumatised", because nothing dramatic happened on a single day. And yet they live with something heavy every day.
That's where the idea of complex PTSD comes in.
What is PTSD?
Post-traumatic stress disorder can develop after someone experiences or witnesses something frightening or dangerous: an assault, an accident, a disaster, war, a sudden death.
It has three main groups of symptoms:
- Re-experiencing: flashbacks, nightmares, or intrusive memories that feel like they're happening now
- Avoidance: staying away from places, people, thoughts or feelings that remind you of what happened
- A constant sense of threat: being on edge, easily startled, always scanning for danger, struggling to sleep or concentrate
PTSD is common. Australia's national mental health survey found that around 1 in 18 Australians aged 16 to 85 had PTSD in the previous year.
What is complex PTSD?
Complex PTSD, often written C-PTSD, is recognised by the World Health Organization in its international classification of diseases (ICD-11). It usually develops after trauma that was prolonged or repeated, and hard or impossible to escape, such as:
- childhood abuse or neglect
- growing up with domestic violence
- long-term emotional abuse or coercive control
- being trafficked, held captive or living through war over a long period
C-PTSD includes the three core PTSD symptoms above, plus three more areas of difficulty:
- Trouble managing emotions. Feelings can be overwhelming, or shut down completely. Anger, sadness or numbness can arrive out of nowhere.
- A deeply negative sense of self. Persistent shame, guilt or a belief that you're worthless, broken or fundamentally different from other people.
- Difficulty in relationships. Struggling to trust, feeling close to people, or staying connected, sometimes swinging between needing people and pushing them away.

The difference, simply put

That last row matters. With PTSD, people often have a sense of who they were before the trauma. With C-PTSD, especially when it started in childhood, there may never have been a "before". The effects can feel like part of your personality rather than something that happened to you.
Why it often goes unrecognised
C-PTSD frequently hides behind other labels. People may have been diagnosed with depression, anxiety, BPD or addiction, and those diagnoses might all be accurate. But if the trauma underneath isn't recognised, treatment can keep missing the point.
Some of the signs people tell us about:
- "I always feel like something bad is about to happen."
- "I don't trust anyone, even people who are good to me."
- "I feel ashamed all the time, but I don't know why."
- "I'm either feeling way too much or nothing at all."
- "I drink because it's the only time my head goes quiet."
C-PTSD and BPD
There's a lot of overlap between complex PTSD and borderline personality disorder: emotional intensity, relationship difficulties and a shaky sense of self. Some people meet the criteria for both. Clinicians often look at a few differences, such as whether fear of abandonment and very unstable relationships are central (more typical of BPD), or whether a stable, deeply negative self-image is central (more typical of C-PTSD). Either way, the trauma underneath deserves attention.
C-PTSD and drinking or drug use
Trauma is one of the strongest predictors of addiction. When your nervous system is always on alert, alcohol and drugs can feel like the only way to switch it off. Many of the people we meet started drinking or using to sleep, to stop the memories, or to feel safe around other people.
This is why trauma and addiction usually need to be treated together. Taking away the substance without addressing the trauma can leave someone feeling defenceless.
What helps
The good news is that trauma responds to treatment, including complex trauma.
Safety and stabilisation come first. With complex trauma, most clinicians use a phased approach. Before going into painful memories, the first step is building safety, routine and skills for managing overwhelming feelings. Jumping straight into the trauma can make things worse.
Trauma-focused therapies. Once there's enough stability, therapies with good evidence include trauma-focused CBT, Cognitive Processing Therapy, Prolonged Exposure and EMDR. They help the brain process memories so they stop feeling like they're happening now.
Skills for emotions and relationships. Approaches like DBT help with the emotional dysregulation that's part of C-PTSD.
Body-based work. Trauma lives in the body as well as the mind. Practices that calm the nervous system, such as breathwork, mindfulness and movement, help many people feel safer in their own skin.
Relationships that feel safe. A consistent, trustworthy therapeutic relationship is part of the healing for many people with complex trauma.

How we work with trauma at Holistic Recovery Bali
Deep-rooted trauma is one of the areas where HRB is different. Many rehabs focus on stopping drinking or using and treat trauma as something to look at later. For us, it's often at the centre of the work.
Because we work with one client, or one couple, at a time, we can go at your pace. We understand that for people with complex trauma, feeling safe isn't automatic, and we hold space for that. We don't push anyone into painful memories before they're ready. The first weeks are about stability: rest, routine, good food, movement and learning to settle your nervous system, including with 9D Breathwork. From there, one-to-one counselling with our team, including David Elsey, who works with trauma and body-centred therapy, helps you work through what sits underneath. Our psychiatrist, Dr I Gusti Rai, oversees any medication.
