Mental Illness and The Brain – What’s Wrong with Psychiatry? Mental illness – is it biological or isn’t? What do you think? I guess I’m a rebel at heart, someone who thinks outside of the box. I know in my own experience, having recovered 15 years from Borderline Personality Disorder, that along the way, on my journey, I had a psychiatrist tell me I wouldn’t get better until they developed some pill – I didn’t believe him. He wasn’t correct. I fired him on the spot after that comment. That was 1987. That was before this notion now forwarded that everything mental illness is a “brain disorder”. Professional in psychiatry are speaking out against the “status quo” of mental illness as a “brain disorder”.
