dawn, I wouldn't get too hung up on symptoms, as I think the important thing is you've acknowledged something is bugging you (or your family) and you're sick of putting up with it!
it's mostly a trial and error thing, as ADD is different for most people, but never finishing things you start, forgetting to do things you promised, thinking of a million things all at once...yeah, that's my symptoms too.
ask your doctor or clinic to refer you to a psychiatrist, since most doctors aren't too willing to listen to ADD problems. (then ask him or her if they deal with ADD)
once you start on your quest, you'll be much better able to deal with things....it's a learning process
