Jennifer Aniston got visibly emotional giving a speech to teenagers and admitted she worries she can't take the heartache she has suffered during her life.
The 47-year-old former Friends star revealed that she has doubted herself several times throughout her career. She was speaking during a Q&A with young girls from all around the world at the Giffoni Film Festival in Italy over the weekend.
Aniston became emotional when asked if she ever woke up in the morning and didn't know who she was.
''There are not enough fingers and toes in this entire room to count how many times that moment has happened to me.
''We're all human beings at the end of the day, whether we're a waitress or a baker or a student or whatever we are, at the end of the day you kind of can hit walls and think I can't go any farther," Aniston told the audience via The Hollywood Reporter.
"Or this is too much. My heart can't take it or the pain is too great, or am I good enough? Will I survive?
'And you just have to sort of somehow miraculously overcome. You just go, 'I can't, yes I can, yes you can.'''

Aniston, who accepted a Lifetime Achievement award at the film festival, urged young people to take social media breaks and emphasised that there is more to life than looks.
'I think we need to empower women to not just be about dresses and beauty and selfies. We need to start having conversations and put our phones down and get out of social media, take social media breaks.
''That's why we're not seeing the right stories being told because everyone is stuck in their phones.''
Aniston, who wed actor Justin Theroux last summer, recently spoke out against body shaming and sexism, after it was suggested that she was pregnant.
