Quick Update: We've started him on Celexa; it's been about a week and a half, it's hard to tell if it's helping yet. He says it makes him feel kind of weird; I know these meds can be kind of dodgy with teens, so I'm keeping a close eye for any weird behavior or suicidal thoughts. All in all, though, the last week or so has actually been pretty decent. he had one "meltdown" but I took him for a drive and got him talking about other stuff.
