Keira Knightley is 30, flirty and thriving — but life wasn’t always that way.

“My twenties were pretty crap,” the “Everest” actress told the September issue of Elle magazine. “My career was absolutely amazing; in fact, I don’t think my career will ever get better than it was in my late teens, early twenties. But as a person, you’re changing so much and you’re trying to figure stuff out.”

Unlike her peers, Knightley wasn’t a fixture on the nightclub scene and sought therapy as a source of release.

“I don’t do it at the moment. But in my early twenties when I found everything completely overwhelming, 100 percent, I did it,” the Oscar nominee recalled. “I think when you’re in those moments in your life, and you want to get through them … you have to do whatever it is to help you get over it. You have to give it a go. Try anything that might help.”

While plenty has changed for Knightley since turning 30 in March — her marriage to James Righton in 2013, as well as the birth of their first child in June — the British beauty laments that daughter Edie has altered her perception of love.

“The love thing is astonishing. It’s a very primal, primal love. That’s quite extraordinary,” she says. “And the ability to have no sleep and continue going. It’s not pleasant — I never thought that I could actually do it for the amount of time that I’ve done it.”

With a newborn as her prime focus, Knightley has eased up on the pressures of bouncing back to her pre-pregnancy shape.

“As a woman, you hate certain parts of your body. You go through those periods where you look in the mirror and you think, ‘Oh, if only I had different legs or arms or whatever,'” Knightley explained. “You go through pregnancy and labor and then feeding the kid and you go, ‘Wow, my body is totally amazing, and I’m never going to not like it again, because it did this, and this is f–king extraordinary.'”
