I just responded over at Latitudes too but wanted to leave another hug as I know how you are feeling. My son was in hospital too with serious med induced psychosis and those kinds of side effects are what eventually led to us weaning him off the drugs and starting the dietary/supplemental/acupuncture etc program that turned things around for him
I hope you will be able to find a different physician to manage your son's care as honestly I would think you have zero confidence left in that psych
hope things stabilize real quickly
