Complex Post Traumatic Stress DIsorder C-PTSD
Complex PTSD is where several traumatic events have occurred, usually in childhood, and which have a massive ongoing impact years later.
I see it a lot with survivors of institutional abuse, sustained abuse over years, survivors of regular violence in the home and so on.
Trauma is a 'psychological injury' it's a result of the impact of what happened to our mind and make-up. In that it's different to many other issues which come about in less immediate ways.
Thankfully there are therapies available with solid track records to help overcome traumatic issues.
