Robert Pattinson has claimed that fame can inevitably lead to mental health issues, saying that he spends a lot of time "constantly worried".
The actor told The Daily Telegraph that shooting to fame as Cedric Diggory in Harry Potter and Edward Cullen in Twilight caused a lot of concern for his family at the time.
"I just didn't really change. And it was fun. For me," he said. "I had good agents and stuff and I've had really good friends since the beginning.
"So I think when it gets dangerous for people is when you have no friends and you think, 'Oh, if I get strangers to love me then it will fill that hole'.
"And then when it doesn't fill the hole then you go 10 times crazier."
When asked if he thinks fame comes with mental health issues, he said "Definitely", adding: "Pretty much every person I know who's got famous is completely nuts.
"It's just isolation and also the repetitiveness of your interactions with people… It's just weird."
Pattinson, whose latest film Good Time is released in the UK on 17 November, added that when he told his parents he was going to have therapy, they were "literally horrified".
"I was like, 'Why is that a bad thing?'" he said. "There's just this weird stigma. It's so strange… But I think it's a sort of throwback attitude."
Pattinson said that he has "got a lot out of" therapy, adding: "I don't know how you're supposed to do… life [without it]."
The actor also spoke about his career choices since finishing work on the Twilight franchise, explaining why he has never gone for a role in a comic book movie.
"It's because I can't get a six-pack, I've tried for years," he joked. "No, I think it's scary to be sort of synonymous with one part… I've never even auditioned for them."
