I diagnosed myself several years ago. That was solely based on the medically diagnosed Aspies I know and, my commonalities with them. Later, i found the online tests and, did all I could find, RAAD-S included and, every one of them verified what I already knew, I am an Aspie, perhaps a very high functioning one when it comes to the social aspects but, I have lived a life that forced me to learn to socialize with some of the elite of society. Had I not allowed my talents to carry me into that world, I would not be as socially adept as I am, and I would make far more mistakes than I do now.
I still cannot read subtle, non verbal cues at all, I give too mush information routinely and, I do not know when to shut up when I am talking about something I am interested in or, talented with. I have also never mastered the art of self deprecation, or verbal modesty. if I am good at something, then that is simply a fact, not boasting. I will not say "My bad" or apologize unless I honestly know I have erred, doing so would be lying yet, NTS do it quite often. I know to get a laugh or ease tensions but, it is not honest and, that is not me.
If I were in your place now, I would want to do the tests, even if I would never seek a medical diagnosis. I would want to erase any doubt form my own mind. I think it's better to know you have a deficit or problem you cannot change than to struggle with trying to change it and, fail repeatedly. You can accept what you cannot change or control but, you can't do that if you don't know the reason for the things you know are not normal about you.
