Emilia Clarke was in "consistent fear" of having "another brain aneurysm" following her 2011 health scare.
The 'Game of Thrones' actress went straight back to working on the HBO show eight years ago after having emergency surgery following a brain aneurysm, and has said she developed anxiety whilst on set because she was constantly worried she would have another dangerous aneurysm.
She said: "I had the consistent fear that I was going to have another brain aneurysm. I spent a lot time just being like: 'Am I gonna die? Is that gonna happen on set? Because that would be really inconvenient. And with any kind of brain injury it leaves you with a fatigue that's indescribable. I was trying so hard to keep it under wraps."
Emilia's condition was so sensitive at the time, that she even had to bow out of a scheduled interview after filming a scene for the show in a hot desert in Croatia, because she had developed "heatstroke".
But the actress says she "never put self-health first" whilst filming the popular fantasy series, because she didn't want to let anyone down.
She told Entertainment Weekly: "In all of my years on the show, I never put self-health first, which is probably why everyone else was worrying, as they could see that. They didn't want to work me too hard.
"I was like: 'Don't think I'm a failure; don't think I can't do the job that I've been hired to do. Please don't think I'm going to f*** up at any moment.' I had the Willy Wonka golden ticket. I wasn't about to hand that in."
