I was starting to get the "ADHD" comments so I took out the book:

Misdiagnosis And Dual Diagnoses Of Gifted Children And Adults: ADHD, Bipolar, OCD, Asperger's, Depression, And Other Disorders by James T Webb.

It helped a lot and clearly showed me that she doesn't have ADHD.

I think I gave you a ~hug~ in your other thread because my two girls are very overwhelming as well. My DD4 sounds so much like yours down to the regressing when littler kids are around!!
