"Yesterday was the anniversary of my brothers passing. There hasn't been a day that's gone by where I haven't thought of him and missed him," the 29-year-old mother of three captioned a photo of Michael. "I know he is watching over me and my family though from all of the amazing signs he has given us. Love and miss you so much, Mikey."

"I had to be strong for her and my whole family, so, that's what I've been doing," Kristin said at the time. Check out the video below to hear more from her emotional interview.
