We all know Megan Fox rambles A LOT, but we didn’t know why until now. Today, Fox said that she's struggled with mental health problems since she was young, and she is convinced she shows symptoms of schizophrenia. How was she able to diagnose herself? By reading every book ever written about Marilyn Monroe—who incidentally did not have schizophrenia. She told Wonderland magazine, "I could end up like [Marilyn] because I constantly struggle with the idea that I think I'm a borderline personality—or that I have bouts of mild schizophrenia. I definitely have some kind of mental problem and I haven't pinpointed what it is." [Yahoo] Well, at least she knows there’s a problem and it’s more serious than a pair of toe thumbs. But does Megan know that schizophrenia doesn't happen in bouts? Does she even know what it is at all? Megan, please seek professional help before deciding on a diagnosis! After the jump, a few more celebrities that have been vocal about their struggles with mental illness.
