Early this year I took the AQ (Autism/Aspergers Quotient) test on this site. It was a complete whim. I had no idea about these things. It is a quick screening test, just a few minutes. I got a high score, well into the Aspergers range. It was a WTF moment.
It has been a long and arduous self exploration since then. I have learned I have been affected by Aspergers my entire life. It has been the root cause of almost every suffering issue.
The test is here on this site:
Autism / Asperger's Quiz
Be warned that a few of you will get high scores. If you do, redo the test paying very careful attention to your answers. Report yourself as accurately as possible.
Finally, a strong caveat: A high score is likely to change your life and it won't be easy.
