"When I found her I really didn't know what to do, because I really didn't believe it," said Kaitlin, whose mother hung herself in the woods by her home on October 5. "I felt like I was in a movie."

Kaitlin's YouTube video has touched many people's lives as it's made headlines and reached over 400,000 views -- just one of the reasons her friends call her "one of the strongest girls [they] know."

"If I could tell my mom one thing right now, it'd probably be that I love her and that I miss her," Kaitlin said. "This whole experience has made me realize that life is short and it's not worth it to fight with people because you never know when the last time you're going to see them is."
