Teen Mom is, without a doubt, the most addicting reality show that MTV has ever produced. While we’ve continued to follow the lives of many of the cast members over the years, it’s been inspiring to see how the women of the show have come through hardship. And for every single person on the show, some would argue that star Jenelle Evans might have had the hardest road of all, as she suffered through everything from breakups to a heavy addiction, and now she’s telling her story in a new memoir hitting book stores this summer.

In an exclusive sneak peek, the reality star shares the truth about her addiction to heroin and how she managed to come out clean, sober, and happy on the other side. “My first trip was amazing,” Evans said, adding, “I won’t glamorize the drug by going into the long details of why people love it so damned much.” But, like many people who experiment with hard drugs, it wasn’t just a fun recreational activity. “Before I knew it, I was shooting up four or five times a day.”

Of course, drug use meant that Evans lost family and friends, first disowning her parents and siblings, and then eventually her friends. At the time, Evan’s mother forbid her from seeing her son Jace, and while she was hurt, it’s clear to her now that it was for the best.

After having a black-out episode and realizing her boyfriend at the time “didn’t love” her, Evans got sober, and when she was released from detox, the first person she ended up calling was her mother. “For all of our problems, I owe her for what she did that day. I called her and told her what kind of trouble I was in, and how I needed help.”

While she’s still struggling with custody of her elder two kids, Evans had a bit of a reprieve with her mother, getting more time to spend with her eldest after the most recent round of family court. Evans had a third child, a daughter named Ensley Jolie Eason, with her boyfriend David Eason one day after Teen Mom alumna Chelsea Houska had her second child.
