Does anyone know whether there is a link between these sensitivities and susceptibility to depression?
Now that is an interesting question to ponder. I recently responded to Dr. Ruf's blog about eating disorders(
Link to Blog) because after reading it, I thought "wow", that WAS me (only I didn't have an actual eating disorder, but close)... eating disorders tend to be higher in those girls (and boys) who have issues with anxiety, OCD, depression, etc... all of which are more common in gifted kids with those overexcitabilities.
And while I can't answer your question myself, I wouldn't be surprised if there is one.
