During Ozzy Osbourne's year-and-a-half relapse into booze and drugs he reportedly got so high he became convinced Sharon was planning to murder him. She finally walked out after he went six days without sleeping or showering; at times, he had gone missing for hours or days. "He was screaming and sobbing 'They are trying to kill me. Sharon's trying to kill me.' It was horrendous. It was heartbreaking for her," a source says. Last week, TMZ examined a 911 call Sharon made in January, which makes it seem as if an "incoherent" Ozzy may have accidentally set a table on fire with a candle. Sharon reportedly won't take him back until he's been sober for months.
