Jess Glynne refused to socialise as she recovered from vocal surgery.
The 'Not Letting Go' hitmaker showed she was back on form as she wowed crowds at last night's (25.10.15) MTV Europe Music Awards, but admits there was many "depressing" points during her recovery.
She told The Sun newspaper: "It was grim. I didn't socialise as it was too depressing."
Meanwhile, the 25-year-old singer previously revealed she was banned from partying as she recovered from the surgery on her vocal cords.
She shared: "I have to be careful [following surgery]. I just need to make sure I rest my voice. I'm not allowed to go out and party because I'm still in the recovery period.
"The record label is working me pretty hard. They tend to put things in your diary without your consent. But now I'm like, 'No I can't do that.' My attitude is that if you want to f**k up my voice again, then cool, but I'm not prepared to do that."
And the 'Rather Be' hitmaker admits she found it "incredible" when she returned to the stage at V Festival earlier this year but says she was the "most nervous" she has ever been.
She explained: "When Tinie [Tempah] came on stage I had to pull it together. He walked out with this face of proudness and love and honestly you don't think you get that. And I don't think you get that often, but there's certain people. It's so special.
"This is my first proper gig back since my operation and being off and that's the most nervous I think I've ever been. I was enjoying it the whole way through, but I just can't control that feeling. It was amazing."
