Seems Amanda Bynes is suffering from much more than bad driving skills, reports TMZ. The actress has been spotted talking to herself, holding conversations with inanimate objects, and "laughing hysterically for no reason," say sources at her LA gym and condo complex. One source even describes her condition as "deteriorating." Her neighbors say they are concerned but haven't notified police or relatives because they don't want to get involved in a high-profile Hollywood story. (More Amanda Bynes stories.)
