Khloe Kardashian says family changed wills to make her their medical adviser after Lamar Odom's hospitalization

Khloe Kardashian really impressed her family with how she looked after Lamar Odom during his hospitalization.

In October 2015, the former NBA pro was put in a medically induced coma after being found unresponsive in a Nevada brothel, and subsequently spent several weeks in the hospital. At the time, Kardashian called off her divorce to Odom so that she could help make medical decisions on his behalf.

In the January issue of Health magazine, the 32-year-old reality star talks about the impact Odom's near-fatal overdose had on herself and her family. "This is kind of dark, but after that, my whole family changed all of their wills so that I would be their medical adviser," she shares. "Because you don't know how someone reacts until you're put in that situation."

Kardashian says she learned something about herself while tending to Odom. "I found strength from within. I was super calm," she says. "I was more like, 'It's greater than you,' and you just get strength. I pray a lot. And I talk to my dad a lot." Her father, Robert Kardashian, Sr., died in 2003 when she was 19 years old.

Just over a year after Odom's health scare, a source tells ET that he has checked himself into rehab. "It was his decision to go back," the source says of the 37-year-old athlete. "He wants to get better and recently realized he needs to do this for himself, and especially for his children. He knows he needs help and unfortunately, this is something he'll need to take care of for the rest of his life. Drug and substance abuse is a serious issue."
