Did it change anything for you? I know for me, getting an official dx went a long ways toward understanding myself and being comfortable with who I am.
I had the same feeling. I can fly under the radar quite well when I'm in situations where I didn't want my aspie side to be as noticable but that's because I was a theatre major and I spent years playing a part. I felt like when I got my dx, I didn't have to play the part anymore. I could just be myself. It took awhile to get used to. I had to figure some stuff out, lost some friends over it who said they didn't like the "new me" (whatever, they never knew the real me because I never let them see it). I used to be myself at home, and be the part every time I stepped out the door but then it got to be too much. I had an honest to goodness breakdown in March because I couldn't hold it in anymore and then I stopped going out. But now, I'm at my most comfortable.
I also have agoraphobia though so social stuff is still hard.
