Fifth Harmony struggling with work schedule

Fifth Harmony are having a tough time dealing with their demanding work schedule as their popularity rises.

The girl group came third on The X Factor in 2012 after auditioning as five wannabe solo stars, but they didn't achieve stardom overseas until their debut album Reflection last year (15).

Their star is continuing to rise with the upcoming release of second album 7/27 this month (May16), and they recently became the first girl group to have a song in the Top 10 of the Billboard Hot 100 in eight years with their lead single Work From Home. But living out of suitcases and never being in one place very long has taken its toll on the girls.

"I love touring, but the schedule ­traumatised me," says Dinah Jane Hansen, 18, to Billboard magazine. "I was like, 'What kind of job are we doing?' I watched my great-grandmother be buried on FaceTime. We're all so family-oriented, and we've all lost people on the road."

"They sell you this ­present of rainbows and butterflies, and as a 16-year-old that's what I bought," bandmate Lauren Jauregui, 19, adds. "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?'"

Camila Cabello, 19, had serious anxiety issues and her heart would beat so quickly that she would be tired after a couple of hours of being awake.

"I was scared of what would happen to me, of the things my brain might tell me," she confesses. "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."

Ally Brooke Hernandez, 22, choked up when recalling her highs and lows of 2015 and mentions "awful mental health situations" and "pain on a lot of levels" without going into details.

In an accompanying video, the girls take part in the #Hot100Karaoke segment, where they try to do singing impressions of Adele, Ellie Goulding, Rihanna and Leona Lewis.
