Westwood only managed four birdies in his 72 holes, three of those coming in his final round of three over par of 73.
It will be a relief to get away from here," said the Worksop golfer.
"I can't remember four more taxing days. It has been pretty brutal out there.
"It wasn't great first thing Thursday morning, it was freezing and you don't expect that in July. It has not really eased up all week.
"But I've been beaten up by the putter. I can handle the weather and I have played pretty well tee to green, but it is just demoralising when you don't turn your good shots into birdies.
"I three-putted the first three holes the first day and that set the tone.
"I didn't have a lot of confidence on the greens coming here but that made it even worse.
"It is never easy when you are getting blown about all over the place, you need to feel you are stroking the ball solidly because you are being buffeted around."
