I live in a smaller EU country and I tried to have a professional check me out, as I have a lot of problems with procrastination, productivity, paying bills on time etc.
I tried asking around (including asking some organization that deal with ADHD in children) for a recommendation for a psychiatrists that deals with ADHD in adults and couldn't get any.
After months of deliberation I finally hyped myself up to get an appointment with any psychiatrist in the local hospital, just to see if they will be of any help and could maybe refer me to someone else. They didn't even seem to know what I was talking about, said that I was obviously fine as I managed to graduate from a university and recommended that I have children to give me a sense of direction in life. So, yeah, good luck to anyone who has adult ADHD here.
It is one of the causes, Europe is more than France/UK.
