Speaking to Extra, the American actor explained that the circumstances in quarantine are difficult for everyone.
“You are at home, you’re not with your friends, you’re not with your family, you are not able to do the things that make you feel worthwhile,” she said.
The 30-year-old continued: “You’re kind of in this costume of depression [sic].”
Johnson went on to explain that it’s particularly difficult to maintain a positive outlook right now when the world is in crisis.
“Right now, there’s also immense pain and sadness ricocheting around the world constantly so it’s hard to feel totally positive all day every day when the world is sad, it’s dangerous and it’s scary and it’s lonely,” she said.
The 50 Shades of Grey star also shared some of her tips for overcoming such feelings.
“Meditation or going for a walk, being kind to your body... Those little things make a difference ultimately,” she said.
It’s not the first time that Johnson has been open about her mental health struggles.
In a recent interview with Marie Claire, the actor, who has experienced depression since her teenage years, referred to the condition as “beautiful”.
“I’ve struggled with depression since I was young – since I was 15 or 14,” she told the publication.
“That was when, with the help of professionals, I was like, ‘Oh, this is a thing I can fall into’.
“But I’ve learned to find it beautiful because I feel the world.
“I guess I have a lot of complexities, but they don’t pour out of me. I don’t make it anyone else’s problem.”
