I'd advise the same thing that have already been said. Asperger's didn't exist as a diagnosis until the late 90's so it's actually extremely common for adults to receive the diagnosis. I didn't get diagnosed until last year (I was 27 at the time), yet as soon as I was diagnosed myself, my friends, and my family realised it made a lot of sense and explained so much about my life. Knowing may not fix these things, but it helps to know why you're 'different' some times.
