Confused

Hi everybody, 

I'm a little confused about my diagnosis 

It says on the front page that I have been diagnosis with ASC

But on the next page it says there are different types of autism.

I've read a lot up about it before I got the diagnosis and was sure I would get diagnosed with aspergers. 

I'm not that clever at all with common knowledge. 

I only do extensive research on things I'm interested in like cars and computer games. And that's the only things that stick in my head. 

I'm absolutely rubbish at maths and English, I struggled like hell in school so I ended up bunking off for the most of it. 

The only reason I got a late diagnosis is because my parents were and still are in denial. 

My mum has asked me "when are you going to grwo up"

Because I'm now 32 and still play computer games.

Thanks for replies in advance
