A new preview of the former Scientologist's interview for Friday's "20/20" aired Thursday on ABC's "Good Morning America." In it, the actress alleges that Scientology gives its young members a false sense of confidence.
"Because Scientologists view children as spiritual beings, you're not treated as a kid, so you're given a lot of responsibility," she said. "Your ego becomes extremely inflated."

During the interview, Remini said that she wants others to understand how she had gotten so deep into Scientology.
"The decision to leave is you are giving up everything you have ever known and everything you have worked for your whole life," she said. "I feel that people need to understand, this has been my whole life. I want them to understand how it happens."
"Good Morning America" will air another preview of the interview on Friday morning. Remini's "20/20" special will air Friday at 7 p.m. on ABC.
