Gwyneth Paltrow's mother has been helping her deal with her split from Chris Martin since they announced the news last month.
The 41-year-old actress has been seeking comfort from Blythe Danner since it was announced last month she and the Coldplay frontman - who have children Apple, nine, and Moses, seven - were calling time on their 10-year marriage.
A source said: ''She is feeling this real sense of failure. She tried to put on a brave face. But finally, as her mum tried to comfort her, she broke down.''
The 'Iron Man 3' star is ''all over the map emotionally'' as she's struggling to deal with the continuous public speculation, while trying to come to terms with her split.
The source explained: ''On one hand, she's glad they're going forward. But this is also such a painful time.
''She's a lot more sensitive than anybody knows. She's absolutely terrified that divorcing Chris will make her an even bigger target for everyone to hate on.''
Although Chris initially wanted to work at their issues and save their marriage, friends now believe he's relieved they've ended their relationship.
One pal told American's OK! magazine: ''There is a big part of Chris that's relieved. The marriage had become extremely suffocating for him.''
