You can't formally be diagnosed with complex PTSD as its not in the DSM. A diagnosis is primarily for insurance purposes. Complex PTSD overlaps largely with PTSD so that's why it didn't get its own diagnosis. And it seems that everyone has a different definition of what complex PTSD entails. There are tests for regular PTSD, none for complex PTSD. I've been slapped with that stupid label and I don't fit the criteria other than having multiple traumas as a child. Funny, as I've never been asked about a number of supposed qualifiers, yet practitioners feel the need to slap anyone with the complex PTSD label if they had childhood abuse and are still suffering. A bit ridiculous.
