An expert is someone with good knowledge in a field of application. An expert proves his expertise by solving problems, i.e. actually demonstrating competence.
There are no mental health experts. There are pseudoscientific frauds who drug everyone they see and end up with more suicides and homicides than if the people “treated” were left alone. This is one of the greatest scams of our time.
From Pete Walker’s website:
What may I have been misdiagnosed with?
Renowned traumatologist, John Briere, is said to have quipped that if Complex PTSD were ever given its due – that is, if the role of dysfunctional parenting in adult psychological disorders was ever fully recognized, the DSM (The Diagnostic and Statistical Manual of Mental Disorders used by all mental health professionals) would shrink to the size of a thin pamphlet. It currently resembles a large dictionary. In my experience, many clients with Complex PTSD have been misdiagnosed with various anxiety and depressive disorders, as well as bipolar, narcissistic, codependent and borderline disorders. Further confusion arises in the case of ADHD (Attention Deficit Hyperactive Disorder), as well as obsessive/compulsive disorder, which is sometimes more accurately described as an excessive, fixated flight response to trauma. This is also true of ADD (Attention Deficit Disorder) and some dissociative disorders which are similarly excessive, fixated freeze responses to trauma. (See my article “A Trauma Typology”.)
