I think I made a mistake..

Hi…. So basically, I got baptised last sunday and I regret it. I don’t regret the baptism as a concept, I’ve been searching for God for a while and I firmly believe having faith in God or something bigger than me is what I need it be able to get through life, but I regret choosing this church. For context, I am from a completely atheist family who give religion absolutely no time of day, I grew up going to Catholic school but had a really terrible experience there and ended up being atheist for most of my life, until I hit a point where’d Id exhausted all other options and the only thing that seemed to help was belief in God. I made really good “friends” in the missionaries (I know that’s the whole point) and I am really grateful that I was able to come closer to God through them, but I really can’t bring myself to believe the doctrine/theology. Maybe it’s the Catholic teaching instilled in me, or maybe because it just seems, respectfully, a bit crazy. I have a lot of Mormon friends who aren’t missionaries, but literally nobody else if my life has any sort of belief in anything, so they were really the only people I could talk about it with. My ward is lovely and people form the YSA ward came to my baptism, and I think baptism as a whole is what I want, but I woke up the next day with feeling of like “ok, you’ve proved your point, now slow down and think about what you really want to commit your life to.” God, yes. This church, probably not. I’m supposed to be confirmed on Sunday but I really don’t want to be, at least not until I’ve explored different churches and even just growing my faith with my one singular Catholic friend (she came to my baptism, she’s glad I found God “even if it’s this way”). I’m not sure what I can do to.. not get confirmed without making everyone hate me, which seems like the way it’s gonna go. I’m happy to still go to church, I’d still meet with the missionaries while they try to reteach and convince me of things I can’t grasp if it makes them happy, but I really don’t think I’ll be able to properly join the church without feeling like a fraud and completely guilty because I just don’t believe it. I’ve read the Book of Mormon and I think there are some valuable lessons in it regardless of how valid or from God they are, so I don’t regret exploring this option, but none of me believes that it’s true and now I feel stuck.
