The church is like a second family for me. I made so many great friends there! Of course it will not be for everyone, but if you are open to it you can try.
Denominations are different flavors of Christianity, and which denomination you visit is important. I'm personally a member of "The Episcopal Church," which I find to have a very small amount of dogma and is tolerant of a wide range of beliefs. The theological dogma can be summarized in the "Nicene Creed," which is a pretty short list of what the church holds to be true (and even if you as individual differ, TEC is chill about that). After that, members of The Episcopal Church are more united in what they do together rather than what they believe togther - songs, taking communion, common readings, etc. The Episcopl Church is generally one of the more liberal/progressive churches around (we ordain women and LGBTQ individuals into the clergy and perform same-sex marriages, for example).
Otherwise, it's a nice group of people that I see every week. A lot of churches have a "coffee hour" or a meal after the service, and it's a time to chit chat with others. They care about me and I care about them, and people check in on each other to see how everyone is doing. When we had a baby, people brought us food, and we always get cards in the mail for birthdays and such. It's nice.
Since we're a community of people, we can sometimes work together to accomplish things I wouldn't be able to do on my own. We run a food pantry and we've supported families fleeing from bad situations (and not in abstract sense, but doing the legwork of finding an apartment in town and providing furniture and stuff). One family attends our services, and their kid is about my kid's age, so we've become friends over that.
Again, I know religion can invoke strong feelings, so if the very idea is offputting, leave it alone, it's fine. But for me, it's been a community I've appreciated having.
