The Osbourne matriarch said that it will take Kelly, 26, a while to come to terms with the singer's untimely death.
'There's nothing I can do to take Kelly's pain away,' she told People magazine.
'This was the first person she's loved who she's lost. That in itself made her frightened and shocked. She's gone through all these different emotions.
'The only thing that will help her is time.'
But Sharon, 58, said that she has already managed to get her head around what happened because she understands that it is all 'part of life'.
'We thank God we're here and we're healthy and we do what we do. But some people aren't as fortunate as us. It's all a part of it. Life and death are as much a part of living, unfortunately.'
