Yup, she took a dive off the deep end, for sure.
All her money aside... the fame part must suck! Imagine what it would be like to have the media on you ALL the time! We take for granted just being able to go get groceries, walk to our car, go see a movie... whatever, without having someone pick apart everything we do. If I throw a used tissue in the trash, I'm happy knowing it won't end up on e-bay!
All that attention has to be insanely hard on someone. I definately could not handle it. I'm going to go out on a limb here and blame the media for her problems. They've been picking on her since she married "Sir Idiot". She's made some mistakes, frankly everyone does, but the media has been especially hard on her. No wonder she cracked.
