Keeley Hawes thinks suffering depression is in her "DNA".
The 43-year-old actress has battled depression for years - and she's convinced she'll always be vulnerable to the illness.
She shared: "It's something that never goes away. I think it is in your DNA if you suffer with it.
"I have become better equipped at looking after myself. I've tried various things over the years. Keeping busy helps, being forced to carry on, because inevitably it will pass."
Keeley also struggles with anxiety, although she considers it to be a very "human thing".
Speaking to the Mail on Sunday newspaper, the 'Bodyguard' actress explained: "It's a very human thing, isn't it, to worry about what you say and how you are perceived?"
Keeley shared a sizzling on-screen chemistry with actor Richard Madden in the 'Bodyguard'.
And Keeley thinks that humour was the secret to their much-discussed dynamic.
The actress - who played the role of the Home Secretary in the popular series - said: "The secret is we didn't stop laughing. You know when someone just tickles you? I felt safe with him.
"We had some very odd things to do together, which means you have to trust each other and I really did trust him."
