CPTSD in the US is pop psychology
When people in the US hear the accurate definition of CPTSD they get really mad and protest. It's completely different than what they believe it is, and refuse to accept it. It has nothing to do with "childhood emotional abuse/neglect" from your parents, or "emotional flashbacks" (which is pop psychology nonsense). It has to with things you don't want to know about and real flashbacks.
It's not a surprise though, most don't even know what PTSD is, much less the more severe CPTSD. Big pharma has done a very good job there making people believe they have "mental health awareness" when it's actually awareness of normal life experience which they've medicalized. People with actual mental illness aren't any less stigmatized and remain unseen, pushed under the rug.
I see psychologists in various countries who are experts in it. The popular misinformation, need for validation, overdiagnosis, etc isn't your fault though, it's largely a result of the industry influence on the DSM. The ICD-11, which is used everywhere else, was made more accurate to try to prevent what happened in the US.
An excellent example of how bad the info is in the US, CPTSD has been in the DSM for more than a decade. There's no 'conspiracy'. The 5th revision added the symptoms to PTSD needed to diagnose CPTSD. People are diagnosed with CPTSD all the time in the US with the DSM. Pretty much all the info you've heard about CPTSD is false.
