The English golfer admits that he found it hard to come to terms with his poor form in the early part of 2025 as he had made a lot of changes to his game following a disappointing 2024.
Fitzpatrick told BBC Sport: "I just didn't have it. I'd put in a tonne of work, my coaches had put in so much work and it just didn't happen.
"There's no stone left unturned for me, but it's hard when you're intending to hit a shot and missing it by quite a lot. I just didn't know what was coming.
"And that's when confidence hits an all-time low and you feel like you can't progress."
The former US Open champion has seen an upturn in results after teaming up with coach Mark Blackburn earlier this year - recording top 10 finishes at both the US PGA Championship and The Open - and credits his family for helping him through the toughest part of his career.
Asked who his biggest supporters have been, Fitzpatrick said: "My mum and dad and wife Katherine.
"She was constantly reminding me that I won the US Open; 'You're a great player, you're going to get it back.'
"It really is true, you've got to have the right people around you and I feel very lucky that I've always had that."
Despite his golfing success, Fitzpatrick admits that football is the sport he is most passionate about.
He said: "People think its a joke but I love football way more than golf. I'm obsessed with football. It's brilliant for me.
"I love supporting Sheffield United, over here in the States they show every game I could wish to see, which is amazing."
