Emily, I think we all go through times of doubt, and when you read stories of prominent Christians you see that just about everyone struggled at times. Some of it is worsened in our day by the attitude that the Bible must be literally factual to be truth. It is ironic that those of scientific bent like this site tend to interpret the Bible as truth in a more metaphysic sense, rather than as a collection of facts.
It helps me to read the Bible as a narrative story, rather than to piece individual verses out that are truly difficult to understand freestanding, and easy to misinterpret.
While it has been said many times before in various ways, read the Bible through the lens of Jesus, and as Christy said so well, place faith in action. It is said that love is a verb, not a noun, and much the same can be said of faith.
