Demi Moore's downward spiral is spiralling worse than you know. Allegedly

Thank you, Us, for setting the record straight. I kinda thought that Demi Moore's downward spiral was a medium-sized spiral; one of those spirals that slows down a bit and let you get back to normal. BUT NO! It's the spiral of doom:

"The night of Demi Moore's Jan. 16 911 call was even scarier than it sounded. "Everyone thought she was going to die," a source tells the new Us Weekly of the emergency, in which Moore, 49, collapsed, and was "convulsing" after smoking an unknown substance. It was the culmination of months of self-destructive partying (and drug use) for the newly single star, struggling to make sense of things as she nears 50 without husband Ashton Kutcher, from whom she split late last year. SHE COULDN'T FIGURE OUT IF SHE SHOULD JUST LIE DOWN ON AN ICE FLOE OR PERHAPS MOVE INTO THE OLD LADIES SANCTUARY. WHAT WE DO KNOW IS THAT IT'S UNSEEMLY AND INAPPROPRIATE TO LET ONESELF BE SEEN IN PUBLIC OR CONSIDER ONE'S PROSPECTS IF ONE IS 50 YEARS OLD. CAVEAT: THIS DOES NOT APPLY TO MEN. "She's been really down, and she's surrounding herself with young people to make her feel better," an insider tells Us of Moore, who's been obsessed for years with staying young and thin. "She's been mixing pills and Red Bulls, among other things," another source says. One of Moore's favorite young stars to party with - and flirt with - is daughter Rumer Willis's longtime friend Zac Efron, 24, a hunk nine years younger than Kutcher, 33. A wired, gaunt Moore "tracked down" the High School Musical star at a party in L.A.'s Venice neighborhood, an insider tells Us. "She seemed out of her mind at this party."
