I asked a Dr. at Johns Hopkins how much she knew about mood disorders and she said "Not much. Maybe in 10 yrs we'll know more". So the field of Psychiatry is small, they don't have many tools. They also told us at Johns Hopkins "Depression is very treatable". Well, why are there so many people in the hospital then? And as soon as they are discharged the beds are filled up quickly; there's no shortage of mentally ill people.
