Amy Adams is a worrier and she’s the first to admit it.

“It feels like I worry about everything—mothering, relationships …,” said Adams in an interview for the December issue of Vogue. “I think it’s because I want to continue to grow; I don’t like being stagnant. Especially when you watch how fast children grow, and what they take into their soul and their intellect. It’s like we make this decision to stop growing. I don’t want to do that.”

Adams, who turned 40 in August, says her worrying has been a lifelong ailment. She thought she might outgrow her worries, especially worrying about what people think of her, but found she just can’t seem to shake off her insecurities.

“I was like, ‘I’m 40 and I still care what people think of me; I still don’t do laundry so I’m always out of things; I’m just not a grown-up at all,’ and I had this expectation that I would be by this age,” said Adams.

“It wasn’t, ‘Oh, I’m getting old and I’m going to lose something vibrant about myself.’ It was more that I was just ‘so disappointed with myself,'” she said in the voice of Katherine Hepburn. “It’s just awful. Any chance for self-loathing!”

Even her three-year-old daughter, Aviana, worries about her mama’s worrying.

“I miss her so much. Ten days is the longest trip I think that I’ve ever had away from her,” said Adams of a recent separation from her family while filming Batman v Superman: Dawn of Justice in Detroit.

“Before I left I told her, ‘Lots of people are going to see you, and Daddy’s going to take care of you.’ We have a huge community of friends,” said Adams.

“But she said, ‘Momma, who’s going to take care of you?’ I said, ‘I’m a grown-up. I take care of myself.’ And she said, ‘No, but you need someone to come and spend time with you.’ Because now she has an understanding of loneliness. It’s very sweet. She says, ‘When I grow up, I am going to be your momma,’” she says with a laugh.

“She’ll probably have to be. I’m such a wreck,” concedes Adams. “I’m glad you think it’s cute now. You’re not going to think it’s cute when you’re 25 and I’m living with you.”
