question: my happy 10 year old has been getting mood swings. he gets lethargic and whiney. Crying at the drop of a hat. His teacher is as confused as I am. One day he is happy and smart the next he is almost fatalistic, and self depricating. He can whip through subjects easily, then the next he says he is stupid and can t do anything. Should I get him checked out? for what? and where? His regular doctor really seems only good for immunizations.
