I’m also in the assessment pipeline in Scotland!
My experience so far: Took visits to three different GPs at my local surgery (first said “I’m pretty sure it’s just your change in life circumstances,” second said “Everyone feels like that though… I’ve never heard of this in adults” and had to go and ask their supervisor so I assume they were new-ish and third said “Are you sure you want a diagnosis? What good will it do you? OK fine, I’ll refer you”) and some additional form filling in and now I have an appointment to see an “adult mental health specialist” at the end of the year. From referral to appointment was maybe… 6 months? I’m not sure, because I forgot to hand in a form for several months (!) and that delayed it.
But I don’t know how the assessment part might go. I’d be interested to hear! For info, I’m late 20s, female, and a postgraduate student which everyone seems to think automatically rules ADHD out.
