He's 13.5. It's been a long time coming. I've wanted this since he was 8 (but didn't actually ask for it until the end of last year). He's typical Aspergers, but the word "Autism" sounds a lot more scary for some reason.
Now what the hell do I do with this diagnosis? He is coping reasonably well at school (he goes to a school with a reputation for excellent pastoral care. They claim it's "second to none" and I'm inclined to agree). This hasn't always been the case, but he's finally settled.
The school knew this diagnosis was on the cards, but I'm not sure now what to do with it, what do I ask the school for, if anything? 
Sorry, I'm panicking a bit here. I probably do know the answers, and need to talk it though.
