He was speaking alongside Michaela's father Mickey Harte ahead of a football game organised by the charity set up in her name.
Earlier this year, two workers at the Legend's Hotel in Mauritius where the murder happened were cleared in court.
John said coming home to the Michaela Foundation provided a positive outlet for the family.
"It certainly was a change of emotions and I was just really glad to be in among family and friends and do something positive for a week," he told UTV.
We've to see things through and that's what I'm hoping to do.
"It was very tiring and taxing out there, [we were there for] a long, long time but thankfully we got through it. It was not what we were looking for in the end, but we came home and relaxed and spent time with the people that love us and you try to just keep yourself up, refocus and we will look further down the line at whatever we can do out there."
John McAreavey is now rebuilding his life and keeping Michaela's memory alive through his work with the foundation, and one of its key events is coming up next month.
Match for Michaela has been billed as a festival of football - and it features All-Ireland champions Donegal taking on an Ulster select.
There will also be music entertainment for the 30,000 fans they hope will attend at Casement Park on 3 November, to help raise funds and to ensure Michaela's legacy lives on.
It has also emerged the family plan to sue the hotel where she was killed for over £1m in damages.
Meanwhile the PSNI have been asked to assist in the new investigation into her murder, after the original inquiry was shown to be hopelessly inept.
John said he would return to Mauritius if there is another trial - and continues to remain hopeful there will be a conviction.
"I try to take each day at a time," he added.
"We are coming round to Christmas which is another difficult time and that brings a new year but I do not know what's out there for me. I just have to take it as it comes."
