Many, many thanks for the lead!
Incidentally, if the SSRIs reduce "rejection sensitivity," then meds that block 5HT might increase RS. Risperidone appears to cut into grandiosity in some teens that I've seen (blatantly so in one of them). They become more "thoughtful" of parents and teachers instead of painting graffiti and driving mom's car at 100+ MPH.
Please stay in touch.
