"He really was the backbone of everything I did."
Wilson was "disappointed" in the judge's decision to vote her off the show when she had never been in the bottom two before.
Her competition, girl group Gap 5, were also up for elimination last week.
"Gap 5 - there's no-one like them and they deserve to be in the competition. But I was disappointed at the judge's decision because they had been [in the bottom two] a couple of times and I didn't get the chance to come back and fight again."
Wilson said she would miss her mentor Stan Walker most from her time at X Factor.
She hoped to keep in touch with the Bulletproof singer and may make an appearance on his upcoming New Zealand tour.
"He was lovely. He was pretty gutted at me leaving, especially because he's on his own now. I think maybe he'll go help Mel."
Wilson believed Greymouth singer Jackie Thomas was the favourite to win the show.
She was planning to use the opportunities the show had opened up to revive her singing career.
But first she would head away on holiday with her husband.
"I'm going to take a nice break in the sunshine."
