Wearing sleek, black leotards and sexy, voluminous waves, Fifth Harmony [1] is the very definition of angelic on the cover of Billboard's May 14 issue.

The girl group — made up of Latinas Ally Brooke Hernandez, Lauren Jauregui, and Camila Cabello [2] as well as Normani Kordei Hamilton and Dinah Jane Hansen — first made their debut on Simon Cowell [3]'s The X Factor, and now they're anxiously awaiting the release of their second full-length (and highly anticipated) album, 7/27, on May 27. But they reveal in their interview with the magazine [4], it hasn't been an easy road to the top. Read on for a sneak peek at what they had to say, and then rewatch their superhot "Work From Home" music video [5].

• On anxiety: "I was having terrible anxiety, nonstop. My heart would beat really fast the whole day. Two hours after I woke up, I'd need a nap because my body was so hyperactive. It was so eff — sorry, but it was so f*cked up. I was scared of what would happen to me, of the things my brain might tell me. I realized the stuff I thought was important isn't worth my health. Now I write in a diary every day, work out and meditate." — Camila
• On their jam-packed schedule: "The schedule traumatized me . . . I watched my great grandmother be buried on FaceTime." — Dinah
• On the illusion of fame: "They sell you this present of rainbows and butterflies, and as a 16-year-old that's what I bought. It's why I did X Factor and why I ended up in a group. But then you're working so hard, so young. [Meanwhile] my friends are in college, telling me about their days and what they're studying. You're having to put on a smile on a red carpet. It's like, 'Who am I? Am I for myself or for this?'" — Lauren
