The couple broke up earlier this year and Garcia, fourth in the world ranking, said it briefly dulled his enthusiasm for golf and his desire to practice.
"I definitely feel much better, happier on the course, and
I'm definitely more looking forward to playing than maybe I was
a month or two ago," Garcia said on the eve of the European Open at the London Club in Kent.
"I haven't been hitting the ball well. I think it's been a
mix of probably being a little bit down and not really feeling
like playing much. Obviously your head is not in the right place and you're
not thinking the right things, and that affects your game
because your mentality is not where it should be."
Garcia won the Champions Tournament in Shanghai in November. Since then, his only top-10 finish came at the Qatar Masters in January.
However, the Spaniard said the people closest to him have helped him get back on track since his break-up with Norman.
On Monday, Garcia visited Turnberry, site of this year's British Open, and it stirred up his ambitions to lift the famous Claret Jug.
"Every time I get to the British Open I dream about the
Claret Jug," he said. "I've always said it, the British Open is
my favorite major.
"I love it, I've been fortunate enough to have two or three
good chances at it and I'm looking forward to having even more.
Let's see if I can get it at least once."
