Key quotes from This is PTSD
"I didn't know how to put my finger on the “what” exactly, other than I had a lot of anger...I was waiting to order my food, and my fists were clenched because I was ready to hit the person in front of me for no reason other than I was angry.”

“She listened to my story and basically told me that she was going to help me and that this was PTSD and it was treatable” 11:13
“Having treated PTSD for nearly 25 years, I can say I don’t think I’ve met a patient who has PTSD that does not have significant sleep symptoms” 22:19
“Before I knew I was on the right path, I was in and out of psychiatric wards. It was not an easy journey, but those trips were there to save me… everything that we had done, the treatments, the medication, the therapy, was working” 24:54
“It will pass, the memories will fade, it does become liveable, and eventually the liveable becomes happiness” 28:08
More About PTSD

Post-traumatic stress disorder (PTSD) is a mental health condition triggered by exposure to a terrifying or life-threatening event, either through direct experience or as a witness. It often involves re-experiencing symptoms, where individuals feel as if they are reliving the traumatic event. These symptoms can take the form of intrusive memories, nightmares, or flashbacks. Such experiences can cause significant distress and anxiety. PTSD is typically not caused by a single traumatic event but rather results from ongoing or multiple exposures to trauma.
To be diagnosed with PTSD, the symptoms must persist for at least a month. Common symptoms include:
- Intrusive memories: often unexpected and relentless, causing intense distress
- Avoidance of people, places, or activities that may trigger memories of the traumatic event
- Reactivity manifesting as irritability, angry outbursts, reckless behaviour or self-destructive actions
- Hypervigilance
- Difficulty concentrating
- Trouble sleeping
PTSD develops when the brain and body remain stuck in a heightened state of stress long after a traumatic event has passed. Normally, when faced with danger, the brain’s fear center, the amygdala, triggers a fight-or-flight response, releasing cortisol to help the body react. In people with PTSD, this response doesn’t shut off properly, keeping the brain and body in a constant state of alert. While traumatic events such as violence, accidents, or natural disasters can lead to PTSD, not everyone exposed to trauma develops the disorder. A key factor in whether PTSD develops is the phenomenological component, the personal meaning of the event to the individual. Deeply personal, prolonged, or betrayal-based trauma, like sexual violence or abuse, carries a higher risk.
Cognitive Behavioral Therapy (CBT), particularly prolonged exposure therapy, helps patients process trauma by repeatedly recalling their experiences in a controlled environment, reducing the fear response over time.
Eye Movement Desensitization and Reprocessing (EMDR), involves recalling traumatic events while engaging in guided eye movements.
Medications, such as antidepressants, can help manage PTSD symptoms and co-occurring conditions like anxiety and depression. In severe cases, certain antipsychotic medications may be beneficial.
