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."
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."
