Jenelle Evans nearly died from a heroin overdose in 2012.

In a new interview, the Teen Mom 2 star revealed that her drug use nearly took her life during the time she was dating Kieffer Delp and living at his mother's home in New Jersey.

Speaking to Us Weekly on July 27, Evans recalled the moment she reached out to her mother and begged for help.

"I quit cold turkey," she revealed. "I just went to my mom’s house and rode it out. I started to go through withdrawals for the first time. I didn’t know it would be like the worst flu I’ve ever had for seven days. First, you have insomnia, then you can’t eat, then you have panic attacks, then hot and cold sweats for a week, uncontrollable shaking and your joints hurt. You can die from trying to withdraw on your own. I luckily did it safely. But I said to myself, 'I’m done. I can’t ever go through this again.'"

As for why she decided to go public with the details of her drug struggles, which were chronicled on Teen Mom 2 years ago, Evans said, "I want to bring attention to how severe the heroin epidemic is. It’s horrible. It is like a disease and needs to be treated like it."

Evans is now a mother of three and planning to get married to fiance David Eason, the father of her yougest daughter, six-month-old Ensley, in September. The couple began dating in late 2015 after her split from Nathan Griffith.
