MEGAN FOX: I USED TO CUT MYSELF

The 23-year-old actress has admitted turning to self-harm when she was growing up as she was so unhappy.

Asked if she had ever cut herself, Megan replied: "Yeah. But I don't want to elaborate. I would never call myself a cutter."

"Girls go through different phases when they're growing up. When they're miserable they do different things, whether it's an eating disorder or they dabble in cutting."

"If I did talk about it, I'd be taking on a role-model status, and I'd have to choose my words very carefully, and I'd have to make sure I reveal it in a specific way, and I don't want to do it."

When quizzed about whether she had ever struggled with an eating disorder, Megan said: "Not that I would talk about."

The "Jennifer's Body" star - who is dating actor Brian Austin Green - added she still struggles with feelings of "self-loathing," and finds it hard to comprehend how successful he has become.

Although she insists her doubts do not negatively impact on her lifestyle too much, she admits they can make her tough to be around.

She told Rolling Stone magazine: "I'm really insecure about everything. I never think I'm worthy of anything. I have a sick feeling of being mocked all the time. I have a lot of self-loathing."

"Self-loathing doesn't keep me from being happy. But that doesn't mean I don't struggle. I am very vulnerable."

"But I can be aggressive, hurtful, domineering and selfish, too. I'm emotionally unpredictable and all over the place. I'm a control freak."
