How to stop hurting yourself? Are you getting anything positive from going to church? If it is upsetting you that much then stop going. Or find one that doesn't rock your boat so much. Something is obviously upsetting you. Or maybe talk to the pastor.

Sometimes those who want to help make things better, end up making things worse.

There is always church on TV if you are so inclined. Or otherwise go to a small group.

If you have to hurt yourself in church something is wrong. Find out what or who the trigger is and act accordingly.
