I’m not all that comfortable with the phraseology of “embracing your disbelief”, because it seems to me that the rejection of one particular irrational ideology by itself would provide insufficient guidance for leading a worthwhile life.
Personally, I found it meaningful to identify what I did believe in, rather than what I rejected. So I consider myself a humanist. If I describe my personal philosophy in terms of theism I’d probably consider the word “nontheist” more accurate - I think the idea of supernatural “gods” is simply irrelevant to life and the world as I perceive them. And I reject ALL supernatural. So why single out theism. I’m just as equally a-witchcraft, a-fairies, etc. To me, they are all equally as irratiuonal and unnecessary to leading a “good life.”
You might find some comfort in reading about other world religions. Once you learn more about other beliefs, and realize how silly their supernatural aspects sound, you may find yourself more comfortable in acknowledging that the supernatural aspects of christianity are just as silly and unfounded. Billions of folks believe in those faiths just as fervently as christians do theirs. I assume you have no difficulty rejecting those many faiths - rejection of christianity is just one more.
Such a study will also allow you to focus on what worthwhile tenets the faith systems share that may appeal to you. Whether a concept of fairness, belief in the value of the individual, human potential, whatever. You may find those provide a firmer foundation for your own personal philosophy, than a somewhat arbitrary supernatural being, the hope of heaven, and the fear of hell.
You also might benefit from seeking organizations that are open to people conducting such personal inquiries. Unitarian Univeralism proclaims itself to be dedicated to a “free and responsible search for truth and meaning.” Other groups include secular humanists, or ethical societies. With any luck, one such group may be active in your area.
You can also get some support from periodicals such as Humanist, Skeptical Inquirer, Skeptic, or numerous books by authors such as Sagan and Dawkins. If nothing else, they will let you realize that you are not alone, and that questions such as you are having have been asked by other people (and perhaps phrased better than you might be able to yourself.)
And there are always the godless heathens who infest these boards during our brief hiatus before an etrnity in the lake of hellfire!
