Hi, can anyone explain the difference between PTSD and Narcissism? After 2 years of verbal abuse from family member that a year ago she was apparently diagnosed with PTSD, after something that happened a long time ago. The lack of remorse for her social media bullying towards us and the cruel words has me questioning what we are dealing with, but because I have a lack of knowledge in both areas hoping someone can shed some light on this. If it is ptsd would be so much easier to forgive & forget and help support her.
