"Teen Mom 2" star Leah Messer has seemingly joined Mastery in Transformational Training, an organization that has been accused of being a cult.

The California-based group characterizes itself as a self-help group and offers a series of workshops that are a "caring, inspirational, and educational environment for generating breakthroughs in the most crucial aspects of your life. You will realize new ways to be more effective, giving and fulfilled in both your personal relationships and your career while experiencing new levels of self-confidence, vitality, joy, and satisfaction," according to their website.

However, one former student's account of what happened in those workshops claimed the training imposed "brainwashing techniques," among other things. That student, Dana Sabre, filed a lawsuit against members of the organization in 2017. The case has since been dismissed, but the claims are shocking.

Radar Online reported the court filing, which read, "Such non-consensual imposition of brainwashing techniques generated massive psychiatric stress, which caused Plaintiff to suffer a psychiatrically diagnosed psychotic break."

The document continued, "Such psychiatrically diagnosed psychiatric break rendered Plaintiff to suffer severance from reality which included cycling among extreme confabulations, violent acting out and a catatonic state requiring four-point restraint and psychiatric hospitalization."

In addition, MITT was also accused of sexual violation, fraud, intentional infliction of emotional distress, negligent infliction of emotional distress, invasion of privacy, and more.

Leah first appeared to make her involvement with MITT known when she posted an Instagram photo on Oct. 7.

"Visualize & Create YOUR reality," the caption read.
