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.

There's no going back. Pray about it if you want. Study theology, talk to people, ect. You are free to figure out what you believe and how you want to live your life. There's no need to throw the baby out with the bathwater.
There's no need to rush telling people about it. Take some time to become comfortable with whatever your beliefs are. Your family might have a hard time accepting it, but give it some time. If their love for you hinges on something like this rather than who you are, they are shitty people.
