Adding on to what Ididitmyway said. The other thing with the diagnoses--are you using insurance at all to pay for your treatment? If so, they require a diagnostic code, and if C-PTSD isn't in the DSM-V, then I imagine there's not a code for it. My T just uses major depressive disorder as the code for me, even though he's acknowledged that I also have OCD and generalized anxiety disorder (and they're really probably my bigger issues and what we spend more time discussing).
