the reason they ask you to take your parent is that you may not remember what happened when you were 2 or 3 years old as autism is seen as only being a developmental disorder if it was present at that age if not it could be another disorder
I'm based in Lancashire - I've got a load of stuff written down to take to the GP initially - if I don't I know that I'll downplay everything and leave with little more than a pat on the head and a load of unresolved queries. I'll take things from there. I'm a bit old to take my parents to be honest - they've been split up since I was a toddler and my mum doesn't even know I've suffered with chronic depression (if she knew she'd make it all about her and her guilt at somehow having failed me, so I've left her out of the loop). The diagnosis or not, is for me, to help me understand stuff about myself and to take positive steps in the future. Thanks for sharing your experiences. It is nice to have a bit of foresight.
