Just over a decade ago, people still thought that PTSD was an incurable condition, but more recent evidence and research proves it is possible for PTSD and C-PTSD to be successfully treated many years after the traumatic event occurred, which means it is never too late to seek help.
For some, the first step may be watchful waiting, then exploring therapeutic options such as individual or group therapy. NICE guidance (updated in 2018) recommends trauma-focused psychological treatments such as EMDR, and trauma-focused cognitive behavioural therapy (CBT). You may also want to explore holistic non-pharmacological therapies, or talk to your doctor about treatment with appropriate prescription drugs.
Traumatic events can be very difficult to come to terms with, but confronting and understanding your feelings and seeking professional help is often the only way of effectively treating PTSD and C-PTSD.
