I can so sympathise with you... I found this quote the other day and thought it might be helpful...

"gifted kids have what Debrowski called an "intellectual supersensitivity" in the 1950's. Basically, this means that gifted kids crave, and need intellectual stimulation like they need food, water and sleep. If they don't get it, they become behavior problems, failures to achieve, delinquent or sick (depressed, anxious, etc.)"

I thought this was quite good for teachers who just don't get it ! ... to help explain how these wee minds work.
