Welcome to Wrong Planet!
I think that people on the higher end of the autism spectrum fall into the grey area between being a fully functional adult, and what the general public would consider a mentality disabled person to be.
I heard someone online refer to Aspergers as "Too weird to be normal, too normal to be weird", I think this best describes how we are precived by the outside world. It's kind of an uncanny valley sort of situation where people can see or feel something is different or off but just can't put their finger on it.
I can also relate to being too high functioning for some things, but also being too low for others. I would suggest googling autistic spiky skill set for more information on this, as it would be little difficult for me to convey through text.
Anyway, I hope you enjoy your time here on WP.
Cheers,
