Hi Aniras,
And welcome. No matter your inspiration, you're a great deal closer to God than you imagine and he, you. I was 14 when I was trying to do the same as you, as you say "figure everything out" and well, 20 years later I'm still trying to figure everything out
At 14, I was going to church for a little while and most of it didn't make sense to me but the people were nice enough. It does make you feel awkward and out of place because you're new and it's hard to know sometimes what's going on. Eventually you catch on. Though I was the mouthy little kid, constantly cussing, people were praying for me as I will you and your family. Not long after I started going to church I prayed and ask God into my life. I didn't even know what I was doing but I knew from that point on that he was in my life.
Having just relocated from the Midwest to southern California, I'm pretty much - once again - in the same place you are; new and observing. One thing I can say for sure is many Christian churches (I've probably been to 6-10 regularly over the last 15 years) welcome children and even feed them a snack. It all takes some getting used to but you will. And there are plenty of churches to try until you get comfortable and I have a sneaking suspicion, you'll find one you really like and stay connected with.
One yet another note you will find plenty of mom's at church to connect with, some around your age and some older. Again, this is probably one of those things that come with (often very little) time. Sometimes you have to be the first to say hi but get connected no matter what. You have questions and better than just posting them here, you'll have someone in person to connect with.
I'm honored to have "met" someone, by the way, who sees the value in community and connection and is willing to do anything to ensure their kids are being raised well. If you really want to start somewhere with them, I'd look around (either online or at a bookstore) for a children's bible. I'm biased of course but the stories are incredibly helpful and insightful and they have pictures
I hope this helps. It's awfully late, even for California, so I'm out of here for now.
Praying for you.
