Ellie Goulding didn't realise her exhaustion was so bad.

The 'How Long Will I Love You' hitmaker took some time off work recently when she was given the diagnosis by the doctor but admits she didn't realise just how bad it was at the time.
She told Stylist magazine: "I was diagnosed with exhaustion a couple of months back, but it's only now that I realise how bad it really was.
"When I think back to my tiredness, my slump, not wanting to exercise and not being interested in anything ... It wasn't depression, it was just my body giving up."
Meanwhile, the 29-year-old singer announced she would be taking some time off in mid July for exhaustion and for fear she would lose her voice entirely.
She shared: "I've had to cancel some festivals this weekend because of exhaustion. I've done nearly 100 shows this year and my doctor has said if I do this weekend my voice might not bounce back from it. They did a bunch of tests on me and I have been diagnosed with exhaustion.
"I'm a hard worker. I don't cancel anything unless I really need to, but my doctor said, 'Ellie, your voice is going to burn out'. Glastonbury was the point where I realised I was pretty exhausted. It's all good though - I'm feeling really positive about the rest of the year."
As well as battling with exhaustion, the blonde beauty also reportedly suffered with severe insomnia earlier this year.
A source said: "Ellie's body clock is completely out of sync and she has found herself lying awake in bed most nights unable to get to sleep.
"All the travelling through random time zones has messed with her system. She just can't get to sleep at night, and even when she's back in England the insomnia is sapping her energy.
"She's worried about it as she doesn't want to be tired before going on stage. She's a professional and wants to give her fans the best performances possible."
