Bethany Joy Lenz reveals decade-long involvement in abusive cult during 'One Tree Hill' years

Lenz became enmeshed in a cult that she initially thought was just a bible study group.
The cult fostered distrust between Lenz and One Tree Hill cast and crew who tried to intervene.
Filming in North Carolina helped create distance that allowed Lenz to eventually leave the cult.
Lenz credits One Tree Hill with saving her life by disrupting her cult involvement.
She is now writing a memoir about her traumatic experience to help others.
