I think the realization that no one else is coming to rescue me was one of the most sobering, scary and liberating things when I finally acknowledged my atheism and made peace with it.
The realization also helped me in mental health therapy, knowing that I was finding (or building) my own pathway to peace and sanity and joy, rather than waiting for someone else to bestow it upon me.
h/t to my friend Edward Brantley for posting this thoughtful meme on his Facebook page.
