Catelynn Lowell is back in rehab for the third time and many of her fans and followers are wondering what prompted the Teen Mom OG star's return to treatment.

According to a new report, the longtime reality star and mom to 3-year-old Novalee Reign decided to travel back to Arizona for more treatment after her suicidal thoughts continued following her previous stints in rehab.

“Her suicidal thoughts before were so strong that therapy two times a week wouldn’t help,” a source close to Lowell revealed to Radar Online on Jan. 22. “Last time was too close of a call. It’s going to take more than a few weeks of therapy to help her recover. If not, he said that she said she’s afraid that things like this will always occur.”

The insider said that in treatment, Lowell will be learning to accept her childhood, her choice to give up her first child, daughter Carly, for adoption, and other "trauma." She'll also be facing other deep-rooted issues that have impacted her mental state in recent months. 

In November of last year, Lowell announced her struggles with suicidal thoughts for the first time and right away, she told her fans and followers that she was headed to rehab to be treated. As fans may recall, Lowell entered treatment for issues of depression and anxiety in 2015 after suffering from postpartum depression after the birth of her second child. 

Although Tyler Baltierra, Lowell's husband, recently sparked rumors of a possibly impending divorce, tweeting that he may not be able to "do this anymore,” Radar Online's insider said there's no reason for concern. As the insider explained, Lowell and Baltierra are completely in love with each another and are both committed to doing whatever it takes to get Lowell the help she needs.

“Ty said once Cate is out of treatment and in a better place they’ll focus on having another kid. A happy ending is what they’re after,” the source added.

Lowell and Baliterra discussed the possibility of having another child during the last season of Teen Mom OG but their plans were ultimately sidelined.
