Not from the very beginning, because my first encounter with Asperger's was in a forum (I don't remember the name) where the Aspies were very negative and blamed themselves for "offending people". They also told me that they didn't think I had AS, based on what I shared, which confused me even more. The whole experience was negative for me and made me feel even guiltier than I'd ever been. So I forgot about it, though AS remained as a possibility in the back of my mind.
Then someone directed me to the article on Wikipedia, which I strongly identified with, and from there I came here, where I've felt at home and elated as you express. I love the attitude here where members don't engage all day in lamenting how flawed we are and how much we upset the poor NTs that have to suffer us.
This place has taught me things I had never been exposed to for even a split second: self-pride, dignity, the value of enjoying life even if alone.
So yes, ever since I've been in WP I've been happy - and I know what you mean about that state of mind where you totally enjoy the music.
