Julia Roberts is still trying to come to terms with her half-sister's death.

The 46-year-old actress told WSJ. Magazine, in a tearful interview conducted just weeks after the former production assistant was found dead: "It's just heartbreak. It's only been 20 days. There aren't words to explain what any of us have been through in these last 20 days. It's hour by hour some days, but you just keep looking ahead."

She added: "You don't want anything bad to happen to anyone, but there are so many tragic, painful, inexplicable things in the world. But [as with] any situation of challenge and despair, we must find a way, as a family. It's so hard to formulate a sentence about it outside the weepy huddle of my family."

The brunette beauty also admitted that she is doing everything she can to cope with the loss.

She said: "Meditation or chanting or any of those things can be so joyous and also very quieting. We share and just say, 'This is a way I comfort myself.' "

It has previously been claimed that Nancy - who had a "complex" relationship with her famous sibling - had left a "ranting" note prior to her death allegedly claiming the actress' fame had driven her to suicide.

Meanwhile, Julia also claimed that she doesn't consider herself to be a celebrity.

She said: "I don't consider myself a celebrity, [at least not] how it is fostered in our culture today. I don't know if I'm old and slow, but there seems to be a frenzy to it."
