Are you squared away in all your thinking except for "religion?" Probably not? Perhaps your intense feeling of confusion is because you sense you need a religion to help you right now, idk.

I don't wish to discuss religion, because that is, more or less, man-made. What you can talk about is faith. You need to choose the basics of your faith, what you believe as premise for your reason for a God in the first place. (You can add religious factors some other time.)

I really think once you find what basics of faith you have, you will know if it fits into something that God says and man in his efforts are trying to follow, or if it is more in choosing of your own. That might be where your initial angst comes from, and not really from any religion.
If you are happy with what you believe, there won't be any more frustration or confusion, imo. If you still have this unsettled feeling, then perhaps it is God who wishes you to change some perspectives. I'm sure if you ask, and are willing to change your mind on some things (if so at that point) He will help you.

Good wishes.
