Hi Jess! Welcome to Atheist Nexus! I wrote a blog a while back (link on my Nexus page) called "A Journey into Atheism". I think, for many, myself included, reaching that point where you can say you're an atheist requires a lot of thought and study and self-analysis. I also think it has to be taken at your own pace. When I first started this journey I found myself clinging to the wreckage of my beliefs (spiritualist, not Christian), but I'm now far more comfortable in my still rather new 'atheist' shoes.
