Wendy, just out of curiosity, has your difficult child ever been evaluated by a developmental pediatrician, a neuropsychologist or a multidisciplinary team at a university or children's hopsital? He has some red flags -- obsessions, not being able to have a give-and-take conversation, not able to read social cues very well -- that point in the direction of Autistic Spectrum Disorder. Mood disorders can accompany Autism Spectrum Disorders (ASD), and the treatment would require both medication and other interventions. The important point is to get an accurate diagnosis so you know what you're dealing with.
