Wilson said he chose to seek therapy about a year ago, a decision stemming from an argument he had with a Newcastle physio during a gym session.
The physio, who noticed a change in Wilson’s mood and demeanour in subsequent days, suggested he would benefit from professional help.
“What I’ve realised is when football and life are going great, you can block it out,” added Wilson, who appeared for England at the 2022 World Cup in Qatar.
“I’ve had a period over the past 18 months where I’ve had setback after setback, things just got on top and basically it was too much to suppress. It all rose to a head and I was like: ‘I need to seek therapy now.’
“I was at a point where I was starting to go back down the wrong path, little things were creeping in like gambling, and I didn’t want to become that person so I needed professional help.
“It took a bit of bravery to realise that as strong as I feel my mind is at times, you also can speak. Even just speaking to her [the therapist] was a great help.”
Wilson began his career at Coventry City and appeared in the Premier League for Bournemouth before joining Newcastle in 2020.
His contract is set to expire later this summer.
In March, he was part of the Newcastle squad that won the Carabao Cup – ending the club’s 70-year wait to win a domestic trophy.
