In my case, the mere knowing was enough for me. Being an Aspie has given me a socially acceptable niche in which I can fit. I am no longer alone in the world.
I have been innately alone my whole life, save my dogs. I have seen counselors since I was about 8 years old. All could tell that there was definitely something sitting me apart from my peers but none could really put their finger on precisely what it was. I felt like I was walking through life in the dark. Without a foundation on which to stand or place my life decisions, every decision I made felt like an hypothesis. I could not relate well at all with peers and did not know why or what I was doing wrong. Depression and isolation was the live standard. I would ask questions that nobody seemed to have answers for. "just do the best you can".... "life is tough"..... "you can do it if you try hard enough".... etc... etc... Doing the best I could usually meant I would outshine the boss and end up unemployed. (Careful what you ask an Aspie for, you just may get it..
