In April 2010, MTV fans were first introduced to Kailyn Lowry when her episode of 16 and Pregnant aired. From there, Lowry was picked as one of only four of the women from the season to appear in their very own spin-off: Teen Mom 2. Now, fans have followed her story for over six years as she adjusted to co-parenting, starting a family with her now estranged husband Javi Marroquin, and she did it all while sharing her life with the MTV crew and, of course, viewers. Over the six years, most fans think they have come to know Kailyn pretty well, but there is a lot that the cameras don’t catch. From details never seen on TV to completely jaw-dropping trauma, here are the 15 most shocking revelations from Kailyn Lowry’s memoir Pride Over Pity.

15. The Drunk Mom

Fans of the series have been introduced to Kailyn’s mom, and her problems with alcohol only a couple times, and now it seems the two don’t have a relationship, but in her book, she opened up about her childhood with an alcoholic mother. Kailyn describes she couldn’t have hobbies or be in clubs or sports because her mother “had enough trouble just remembering to pick me up from school.” She also detailed a time where her mom came to pick her up after drinking and Kailyn had to try to hide it from the teachers. When she was asked about it, she told them her mom was just upset about the events of 9/11 that had happened the day before and was “really shook up.” “I’d like to pretend my mom never hurt me, but the truth is she did. I t felt like a bottle of liquid brought her more joy than spending time with her own daughter,” she wrote.
