"I wanted to leave my mark. I wanted to do my part to change the world," she says.
After almost two years of chemotherapy, brain surgery and radiation, doctors told her the grim prognosis. Rebecca says that's when she decided to come up with a bucket list.
Her bucket list includes simple things like venturing out of the country for the first time, playing board games with her cousins and watching with her parents their favorite movie, "The Shawshank Redemption."
"So many people wanted to help with my bucket list." Rebecca says. "My dad has always told me to be kind. We talked about what we could do to involve everyone that wanted to help."
They came up with "asking people to do acts of kindness."
"It's not easy for me to do acts of kindness myself. I can't walk right now."
Rebecca posted on Facebook
asking if people would perform random acts of kindness and then post about it using the hashtag #BeccaToldMeTo.
And now people all over the world are sharing their good deeds using the hashtag.
"It was supposed to only be used on my last day of radiation. I woke up the next day and it [the hashtag] was still going." Rebecca says.
"It doesn't have to be a monetary donation. Just a smile. Just give your time. It doesn't cost anything, for example, to shovel your neighbor's driveway. Visit someone who might be lonely," Rebecca says. "That's what the message is really. It doesn't matter how big or small your deed is as long as you do something, it will be appreciated."
Meanwhile, Rebecca is enjoying the time she has left with her family and friends.
"Physically, I feel like I did when I was just recovering from chemo. I'm nauseous and exhausted but it doesn't feel like I'm dying. I don't feel like I'm going to die. I feel OK, I guess. As good as I felt before." Rebecca says. "We try not to dwell on it. We focus on the good things. It hasn't really sunk in yet. For the most part, we are not thinking about it."
Her mother, Anne, says Rebecca is just being herself by asking people to give back to others.
"We are grateful for the support she is receiving in the community and worldwide," Anne Schofield says. "The stories that people are sharing, it's pretty amazing. To see her happy makes us happy."
