If you look up complex PTSD via Google you will see a lot of results. Wikipedia, for instance, says:

A differentiation between the diagnostic category of C-PTSD and that of post traumatic stress disorder (PTSD) has been suggested. C-PTSD better describes the pervasive negative impact of chronic repetitive trauma than does PTSD alone.[7][8] PTSD descriptions fail to capture some of the core characteristics of C-PTSD. These elements include captivity, psychological fragmentation, the loss of a sense of safety, trust, and self-worth, as well as the tendency to be revictimized, and, most importantly, the loss of a coherent sense of self. It is this loss of a coherent sense of self, and the ensuing symptom profile, that most pointedly differentiates C-PTSD from PTSD.[9]

And:

Complex trauma means complex reactions and this leads to complex treatments. Hence treatment for C-PTSD requires a multi-modal approach.[40] It has been suggested that treatment for C-PTSD should differ from treatment for PTSD by focusing on problems that cause more functional impairment than the PTSD symptoms. These problems include emotional dysregulation, dissociation, and interpersonal problems.[41]
