Pitman said she would ask God just "for strength to get out of bed and spend some time with the kids."
And God did support Pitman and her family, even during the toughest trial. "The Lord provided and orchestrated everything for us for the entire year," especially by bringing "all the right people into our lives at the right time," she said.
Pitman found particular strength in the scripture passage Matthew 21:21-22, which says in part, " ... but even if you say to this mountain, 'Be taken up and cast into the sea,' it will happen. And all things you ask in prayer, believing, you will receive."
"God was able to move the 'cancer mountain' for our family," she said.
After her battle with breast cancer, Pitman's 17 year-old daughter, Jocelyn, nominated her for Walmart's "Mom of the Year" award, which is a "celebration of the 9.2 million Canadian Moms who work tirelessly every day to provide for their family."
The winner will receive $10,000 in cash and a $100,000 donation will be made to the charity of her choice. The top mom will also be honored with a "day of pampering," a photo shoot and a "special red carpet gala" in Toronto.
Should she win, Pitman will give her donation to Camp Peniel, a nearby Christian camp where her daughter Jocelyn works.
"This camp is amazing and is doing a fabulous job of sharing Jesus Christ to so many each year," Pitman said.
Nominations closed July 8, but the judges will deliberate the 16,909 entries and announce a winner "around August 15."
