I wasn't raised in any religious tradition (except insofar as you could consider my parents' committed atheism a "religious" position). I don't really believe in god but I don't believe in no-god. it's just never been part of my life. But I am really isolated and missing a sense of community. I also struggle a lot with depression and I've considered "finding religion" but I don't really know where you start with that. forgive me if this is a weird question. just something on my mind right now.
edit: i'm not asking abt any specific religious tradition. I live in a big american city so i'd probably have a variety of options but it seems to me that the most likely places would be churches of any denomination or a mosque.
I know Unitarians would be welcoming of you. I can't really speak about others.
I was about to say this. I'd you're interested in the community aspect of church and want to dip your toes into the discussion / group aspects then hit up a Unitarian group.
It may even give you a good idea on how to start or even be a pathway to other community organisations (local councils, community education, reading groups etc.) as Unitarians are generally massive nerds but pretty active in community.
