Of all the tragic trainwreck stories that have been featured on MTV's Teen Mom, Amber Portwood's might be the only one that gives us hope that the controversial MTV reality series doesn't necessarily ruin the lives of all its stars.
Beginning in 2012, Portwood served 17 months in prison on charges of domestic violence and possession of narcotics.
Since her release, however, Portwood has proved that it's possible to live a sober, successful life after one of those all-too-common Teen Mom meltdowns.
In a special about Portwood that recently aired on MTV, the mother of 6-year-old Leah revealed just how bad things got for her at her lowest point:
"I would stay up all night taking drugs 24 hours," Amber says. "Then I would get so high I'd forget I took pills, and I'd take more. A whole script would be gone in a week. That's 180 pills."
Amber says it's difficult for her to watch old episodes of Teen Mom, as she was under the influence for the entirety of the time she was filming the show.
Addiction runs in Amber's family and her father, Shawn Portwood, Sr., died late last year as a result of alcohol-related liver damage.
Amber has hit other bumps in the road over the past few months, including her tumultuous relationship with Matt Baier, but she says she's remained sober throughout all of the drama.
Maybe there's hope for Jenelle Evans, yet.
