That sounds a lot like my dd10 as well -- ADD, anxiety... There are times where the kiddo seems brilliant and there have been times where I'm not sure she is gifted at all.

Depending on how you define EG, though, you could put your dd in that category. DYS calls scores in the upper 140s PG although I guess that that can make more sense if the achievement and other indicators are there (which they would need to be for DYS).
