Help me gain my faith back.

Now I just listened to The God Delusion on tape, love the guy's voice, and now whenever I try to read the Bible I just cannot believe a damn thing in it anymore. Now I am having panic attacks at night and I'm worried for my own safety that I might have committed a sin by reading this book.

I need some help, is there anyways I could forget all that I have read in this book and is there anyway I could cleanse my soul so one day I could go to Heaven and live in peace? I am even temped to listen to it again, even more temped than to go to Sunday School. What if my family found out about this? I need some help Anonymous.
