You'll never feel how you think you're supposed to feel while believing. I've been there. Before you make your choice study evolution, and the scientific method, they WILL coincide with what you were taught, but will make much more sense (Because they're facts). Many creationists complain about evolution being just a theory, the scientific method will help you figure out what a theory is. I am an atheist through and through, but am VERY good to people because it's the right thing to do, not because of some dogmatic moral code. You'll make it through.
“Whoever will be free must make himself free. Freedom is no fairy gift to fall into a man's lap. What is freedom? To have the will to be responsible for one's self.” - Max Stirner.
