If you're an Atheist, what comforts you?

[Angrboda]

Go find a new tribe - or just stay in the one that you're already in, since they're providing all of the above?  It doesn't actually matter whether or not god is real for any of that..right?

Where do I find a new tribe?

Have you considered humanism, whether Judaic or secular? In my experience, humanists are a lot more interested in developing community and ritual than atheists who are not humanists. Unitarian universalism is another tribe, perhaps a bit more structured and organized than secular humanists.
