Michael vehemently disagrees with Susan’s claim. He claims Bodhi is severely autistic, not schizophrenic, and that Susan is endangering him by going from “doctor-to-doctor” in search of the diagnosis she wants for their son.

Susan denies Michael’s claims. She claims that he “cut and run” on her and their marriage and just sees their children “as a nuisance to his new life.”

“I believe Michael wants them both to be institutionalized – especially Bodhi,” says Susan in the video above.

How does Susan respond when Dr. Phil says, “Tell me why you’re so convinced that he (Bodhi) has childhood-onset schizophrenia?”
