this is just mho but..........i have heard that about 80% of people diagnosed with BPD have had trauma histories, and only 20% do not. Well then 80% are misdiagnosed. Trauma is TRAUMA. Complex PTSD has several overlapping symptoms with BPD, but it is not the same. again...just my 2 cents. I am glad I have not been one of the misdiagnosed and that my T gets complex ptsd.
