10 Celebrity Meltdowns

Margot Kidder

Margot Kidder may be most famous for her role as Lois Lane in the "Superman" movies we know from the '70s and '80s. Or perhaps she's most famous for her meltdown that left her missing in Los Angeles in 1996.

In the spring of 1996, Margot was working on a book of her memoirs only to have them vanish at the strike of a computer virus. Days later, she would vanish, too. Margot wandered the streets of Los Angeles, suffering from paranoid delusions. When she was found four days later, she was disheveled and missing her front dental work and most of her hair, which she'd chopped off. Margot was diagnosed with bipolar disorder, a mental illness that causes swings between extreme mania and extreme depression.

Today, Margot is an advocate for drug-free treatment of mental illnesses, treatments that emphasize vitamin supplements, avoidance of wheat and dairy as well as acupuncture and finding a life-balance to reduce stress.
