Kristen Stewart needed control

Kristen Stewart used to make herself ill if she wasn’t in control.

The 25-year-old actress struggled to cope with her  »intense » early success and was  »constantly anxious » worrying about what could happen.

She said:  »Between ages 15 and 20, it was really intense. I was constantly anxious. I was kind of a control freak. If I didn’t know how something was going to turn out, I would make myself ill, or just be locked up or inhibited in a way that was really debilitating. »

Kristen – who causes a scandal in 2012 when it emerged she had cheated on then-boyfriend Robert Pattinson with her ‘Snow White and the Huntsman’ director Robert Sanders – admitted she has become more  »feral » and less concerned about her image in recent years.

She said:  »Lately, I’ve been doing less of the ‘I’m sooooo sorry.’ And more of the ‘No. F**k. Jesus.’…

 »Speaking very candidly, it was a really traumatic period in my early 20s that kick-started something in me that was a bit more feral. »

And the ‘Twilight Saga’ actress – who is rumored to be dating her assistant Alicia Cargile – is  »proud » she is learning to be a  »smarter and calmer » person.

Speaking to America’s Marie Claire magazine:  »I’m really proud that I am able to move forward and not fall into every mental crater. That’s a new thing for me. Age has made me smarter and calmer. And it is f**king awesome. »
