happiness is such hard work
That doesn't sound enough like autism that a diagnosis does you any good.Autism (possibly Asperger's), Tourette's and I used to be bipolar.
Fortunately my Autism is very mild and manifests itself in emotional detachment, mental maths skills, lack of social skills and a like for order and structure. My brother is similar, Autism with SAD that he has thankfully supressed.
Also IQ is relatively irrelevant - It's useful at a young age (like 5) to figure out if you're bright, but otherwise not useful or anything but dickwaving.
It's also worth noting that IQs approaching 150 become relatively difficult to quantify as specialized tests are needed for a >150 accurate score, and not a large enough sample size exists to make these tests.
My IQ is 148, for what it's worth.

Also stop putting "disorder" in front of every damn problem you have - it just encourages you to feel helpless and make no effort toward self improvement as a result.
