When Kristin Cavallari lost her brother Michael last December, she was forced to pick herself right up to care for her children.
Cavallari had just welcomed daughter Saylor one month earlier.
"I still do find a lot of strength in my children, because of the timing of everything," Cavallari told Us Weekly. "You can’t just stay in bed and feel sorry for yourself. You gotta get up. You have other lives you have to take care of. You have to put food on the table and get them dressed and off to school and everything. So yeah, you can’t just feel sorry for yourself."
The former reality star has three children with husband Jay Cutler.
Michael Michael Cavallari died of hypothermia after he crashed his car during a frigid temperatures while passing through a rocky and rural part of southern Utah.
