I think many people with complex ptsd have been diagnosed with a personality disorder. I'm not saying it's correct~ i'm just saying there is a difference between PTSD and Complex PTSD.

Complex PTSD - PTSD: National Center for PTSD

I think it's important to get the correct diagnosis because otherwise people with complex ptsd being treated as if they have ptsd will always have a lost feeling. PTSD does not address the issues that come from the severe psychological harm that is associated with complex ptsd.

I wish you luck!
