I was diagnosed with autism as a child and recently had to go through another assessment for work purposes to "confirm" the diagnosis and provide guidance for workplace accommodations.
I had this paper done by a psychiatrist who was so ridiculously unprofessional (he was in his pajamas on one occasion when I met him! Amongst other things, mostly about his manner) and I feel having that particular, poorly written diagnostic paper on my file with my employer will hinder rather than help, particularly if I move into other roles. I'd also like to have something proper on hand for personal reasons.
So here I am considering going through a formal diagnosis again and I have some concerns about what is required of me as an adult. From my understanding from this particular psychiatrists website, the process requires some involvement from family members who knew me as a child. Unfortunately I do not have that anymore, for reasons I am not able to explain on an open forum - but understand that they are not dead. I am reluctant to provide the diagnostic paper from the last psychiatrist for background information because it is poorly written in terms of its contents and lack of detail.
Have any adults here had a diagnosis without participation of family? I know the basics about my childhood (age I started walking, talking, motor skills and so on)
