The singer, 30, known for hits including Ciao Adios and 2002, said she decided to use lockdown to “make the most of the situation” and work on herself.
Anne-Marie said she had faced her anxiety and fear of judgement, suggesting taking a year out of the limelight was “needed.”
Speaking to the Standard, Anne-Marie - who is originally from East Tilbury in Essex - said: “2020 was a big life lesson for me. It was horrific, and it was a bad year and so many people have been through tough times. But I tried to make the most of the situation that we were dealt with.
“This year has been one of my favourite years so far in my career and as a human. I started therapy during lockdown and it really helped me figure things out. And start to like myself. It sounds so sad. I have had anxiety for so long and worried about judgement and wondering if people like me. It is a big thing and when you love yourself, everything changes, and everything is better.”
The star - who has named her upcoming album Therapy - continued: “I got so low, and sad really, that there was only one way to get out of that and that was to face everything head on. Thanks to that year, I can live a life that is much happier. It is a weird juxtaposition really. It was one of the worst years in the world, but for me, maybe, it was needed.”
The star, who appeared as a judge on the latest season of The Voice alongside WIll.i.am, Olly Murs and Sir Tom Jones, said her newfound confidence meant she would love to do more television work.
Anne-Marie - who has also appeared on Celebrity Great British Bake Off and Gogglebox - said: “When I did the Bake Off, I loved it so much, And with the Voice I really liked that people could see me with my personality and not just my voice. They could see me as a person. So it was a great thing for me to do.”
