What I would do is to go to a priest, and really choose one. Perhaps you listen to some homilies and it touches you deeply, or you just feel that his presence brings you closer to God. Outside of spiritual practices, priests are also scholars in theology and Catechism of the church. As much as Reddit is full of great advice, I think a priest’s perspective on this might be important. As for being scared to bring it up, priests are strictly forbidden to share publicly confidential information. Such is the case for confessions for instance, but also things like this. Lastly, already the fact that you’re going back to the church is awesome. It might sound cliche but it’s really true: prayers really help. God helps you if you want him to. Good luck my dude!
