I'll give you some advice only because it worked for me. If your willing, put your life in God's hands. For better or worse, richer or poorer. Give God the burden of your certainty. It's ok not to know. You have to let go of all your expectations and go forth as an empty vessel waiting to be filled.
It seems that God wants us to trust in him and not anything else. No religion, no books, no priests. If the Holy Spirit comes to you, you will know. You won't have to guess. However you won't be able to claim ignorance afterwards.
Sometimes I think it would have been better to have remained ignorant. At least I had an excuse for my actions. I was a horrible person. It's not easy to face the truth of that.
Sorry, I'm not trying to be preachy or mystical. It just comes from personal experience.
