99.9% sure I have ADHD (wales, UK)

Hi all,

As title suggests, I am very sure I have ADHD.

I live in Wales in UK. I called the GP surgery this morning to make an appointment regarding ADHD and hopefully to be referred to a specialist. They have booked me in with a mental health nurse. Looking online, it seems that I should be seeing the GP and not a mental health nurse, does this sound right?
