Getting diagnosed

How is the normal way of getting adhd diagnosis in your country? Especially when your an adult who haven’t got diagnosed as a kid. In Germany it’s pretty difficult for an adult to get the official diagnosis. I have to see my normal doctor in the first place, than a neurologist who now send my to the adhd specialist where I have to do a 3 day psychology test. And I have to wait 15 months for this appointment. After all that you also have to prove, that you already had adhd symptoms as a kid (under the age of 12) that causes you problems. It must affect at minimum 2 parts of your current life. Only after all that you can get a diagnosis and therapy or / and medication. So I was wondering if that’s the same procedure in other country’s?
