Question from active lds (delete if not allowed)

I am active lds, I was kind of roped into becoming a teacher to a primary class, I’m the kind of person that doesn’t say no when asked to do something, I really don’t believe in the religion, I’ve found a way to make my lessons Christ focused instead of the sincerity and truthfulness of the Mormon gospel and doctrine, like I said, I don’t believe in the religion, I’ve seen things in the church that can only happen to people that god doesn’t care about, suggestions on how I can break my ties with the church? Like I said it’s hard because I’m involved in the class as a teacher, and I’m also a ministering companion for some people who want to learn about Christ, and I would love to teach them, but I just don’t want to do it in the lds perspective
