Troubled actor Nick Stahl has left the Los Angeles hospital where he was placed on a 5150 (involuntary) psychiatric hold earlier this month, TMZ said. \"It\'s going good,\" the 33-year-old actor told the celebrity news website\'s cameraman, who spotted him out and about this week. Questioned about his recovery, Stahl replied: \"It\'s going. It\'s a process.\" Known for his roles in the films \"Sin City,\" \"In the Bedroom\" and \"Terminator 3,\" as well as on the TV show \"Carnivale,\" the actor has long struggled with addictions to drugs and alcohol. His estranged wife has also reported him missing to police several times in recent years. Stahl told TMZ \"stress\" and \"life problems\" led to his hospitalization June 17, but he didn\'t elaborate. Asked if he thought the 5150 psychiatric hold on which he was placed was necessary, he replied: \"I don\'t know. It was helpful.\" Section 5150 is a section of California law that allows for the involuntary confinement of a person deemed to have a mental disorder. Stahl did not say exactly when he left the hospital.
