I hear what people are saying. However there was a professional on the thread earlier who said that it is not a myth that there is a stigma around ADHD/ASD and if not handled carefully, a diagnosis could negatively affect self-esteem. So I don’t think I’m being foolish in considering all potential ramifications. If a person is struggling in social situations, for example, how does a diagnosis actually help?
Ime, it's the condition and the negative labels from other people, that damage the self esteem; not the diagnosis!
DD has ADD and I could write a long list of all her problems with her executive functioning - forgetting appointments, losing things every day, the disorganisation, the inability to comprehend conversations/books/films, the hyper emotional states, the inability to understand instructions....and how they impacted her school work, her friendships, her relationships....They and the stupid comments by teachers, who called her scatty, etc, were what affected her self esteem while she was at secondary school, long before the diagnosis at about 22! (I first took her to the GPs for antidepressants to get her through her A levels)
It is also nonsense to say ND people can't succeed in the professions. DH has ADHD and OCD (exactly the same as DD, but hyperactive with it) - he became a partner in our profession, because he applies hyperfocus to his work, just as DD did to her degree, and she got a first (although the university made considerable reasonable adjustments)!
As an adult, it is up to them whether they disclose the diagnosis to anybody else! They don't have to!
