By the way, the ADD testing is a lot like the testing on this site. In fact, there is a place on this site where you can view the tests. However, don’t study for it. Just go to the doc, be your own lovely self, and answer the questions honestly. It’s really no big deal. Getting the right kind help is most important.
Oh, and this: You said, “At times in life I’ve been a tremendous daydreamer. I spent most of my elementary school hours peeking ahead in the textbooks, rather than listening to the teacher. ”
Also a sign of a giftedness. Sometimes one gets mistooken for another. My daughter is highly gifted, and does this. She also probably has a touch of ADD. Well she’s practically perfect, in my humble opinion 
Then it got hard for you. There’s a video on here where a woman talks about how girls with ADD will do fine in highly structured environments, and then it gets harder as the structure becomes less and less as she proceeds through schooling.
Seriously, call your doc. What do you have to lose, here?
