Thanks everyone. The psychiatrist is not convinced that Prozac is the cause of DS's increased anxiety, but I definitely have seen a correlation when he went from 10mg to 20mg. When he started 10mg he was fine, but 10-20 has been very difficult.
As of today, we are dropping him back to 10mg Prozac and adding Abilify. We'll see if that can get us through to the next appointment. I understand that upping the Prozac can cause short-term problems for a few weeks. But in the meantime, DS is suffering - depressed / manic, crying over little things and missing school. This is ridiculous and my wife and I can't just let this go.
I'm tempted to put the plug on meds, but we put him on them because we had a similar episode (though not as intense) when he was off meds this Spring.
I'm very concerned. Ugh.
