Similar to PTSD but where the trauma is often inflicted by a person close to the sufferer and occurs repeatedly (sustained childhood abuse or domestic violence) and/or is layered with systemic trauma (oppression, racism, coercion). Overlaps PTSD symptom clusters with emphasis on depersonalisation/detachment (especially where repetition is still a likelihood), ongoing trust issues, negative self view, emotional dysregulation and loss of core beliefs, values and hope.
