Young actress Chloe Grace Moretz is convinced she has battled a form of Post-traumatic Stress Disorder (PTSD) ever since her father abandoned her family as a child.

The actress was in her formative years when her dad, McCoy, left her mother, Teri, to raise Moretz and her four brothers as a single parent.

"I was 12. It was a pretty bad experience," the Carrie star recalled to Glamour magazine.

"It could have rocked our family and messed us up, but it actually made us a lot tighter," she explained.


"My brothers bumped up into the roles of fathers and kept me in a bubble where I could live in a world that wasn't jaded and ruined."

Her parents' divorce still pains Moretz, now 19, and she doubts she will ever be able to repair her fractured relationship with her dad.

"I don't think I will truly find a way to forgive," she admitted.

"The things that he did are unforgivable ... My forgiveness is that I'm living my life."

The young star admits she still struggles with some lingering trust issues as a result of the family split.

"In my business in general, it's hard to trust people," she said. "And it definitely affected me at a young age in terms of accepting people into my life on a personal level."

"But I've overcome that in the past few years - dealing with relationships, dealing with guys. You don't realise why you're acting a certain way, and then you start to piece it together, and you realise you've got a slight case of PTSD."

Moretz credits her older brothers - Trevor, Ethan, Brandon and Colin - with helping to really look out for her and weed out fake friends, but that also means they're pretty tough on potential suitors.

"They peeled back when I turned 18, but yeah, it's like I have four bodyguards," the actress, who has reportedly been dating David and Victoria Beckham's son Brooklyn, said.

"When a guy comes to the house to pick me up for a date, I enjoy them answering the door, shaking his hand, and then him being like, 'Your brothers are kind of scary.' I'm like, 'They are definitely very scary.' I enjoy the power of that."
