Harry Styles apparently has fear of staying alone so much so that he wakes his personal trainer to work-out at night.
The 19-year-old singer struggles with his emotions when he is away from his family, even though he enjoys seeing the world while touring with his band.
According to British magazine Heat, the 'One Direction' singer suffers from terrible homesickness and exhaustion towards the end of the tour, Stuff.co.nz reported.
Another reason behind Styles' homesickness is that, even though he gets along with the rest of the band members, he requires time-out from them as well, as he likes to relax with people who have nothing to do with work.
