I got an autism diagnosis late last year, after suffering with mental health etc badly since I was maybe 6-8 years old, I'm still not 100% sure if it's just autism , but anyway.... I had to go to the GP first, then she referred me , then my parents were spoken to (I'm 20) about my childhood, then I was spoken to and had to do different tasks, then wait months for anything back... so I wonder if she had any other tasks or anything done to work out if it's what she is suffering with? I just don't fully understand how it could be diagnosed fully in one conversation, unless she didn't post/film everything but I don't know, I'm conflicted over whether you can get the diagnosis that quick..
