Girl who "married" best friend loses battle with cancer

Eileidh Paterson from Scotland was only 5 years old when she started working on her bucket list. That's because in 2014, she was diagnosed with high risk neuroblastoma -- an aggressive type of childhood cancer.

After spending the majority of the past three years in hospitals undergoing treatment and surgeries, her oncologist concluded Eileidh would not survive long-term. So her mother started a GoFundMe page to help raise money so that she could create as many memories as possible. She wrote at the time, "Anything we can do to make her life that little bit easier, comfier & most importantly magical, then we owe that to her & she most certainly deserves it."

You can watch the video above to see how Eileidh's dream came true before she passed.
