I am a women in my 50's. A number of years ago I was diagnosed with a personality disorder. After years of depression and meltdowns I finally got an assessment for autism. I have had private and nhs assessments which both conclude I am autistic. Following an appointment today with mental health services it appears that the only route they want to go down is regarding my personality disorder which I feel was a misdiagnosis. How do I get them to accept that this was a misdiagnosis and start to help me with my autistic difficulties>
