When you realize that all you were taught about religion is wrong, you can dismiss what you were taught. Anytime those teachings cause torment in your life, just dismiss them. Do your best to unlearn anything negative and rethink everything positive to a secular viewpoint that you can feel more comfortable with. When engaging with loved ones take comfort in knowing what you know. Avoid church other than weddings and funerals. It's okay to be an outsider. Think of it as sitting through a boring movie that you can't walk out of. It'll be okay, it'll be over eventually. Don't let this stuff make you go nuts. It's not worth it.
