I had something similar. I grew up catholic and was very devout until I learned some stuff about myself that made me step away for a while. I expected to come back like a year later and join the episcopalians or something, but I wound up an atheist for several years. During that time I was kinda insufferable about it for a while. Then I started exploring pantheism, earth worship, and ancestor devotion because I’d felt I was missing something without religion and lighting candles to talk to my mom helped me cope with how much of my life she doesn’t get to be there for. Later an acid trip and some exploration would help me delve deeper and find the goddess I primarily pray to these days. Somewhere later I started using the Wiccan holidays because they’re really convenient for solar and seasonal observance and meditation. They also help make it so I don’t wonder where the hell the year went.

So yeah, catholic to atheist to pagan. There are many paths up the mountain, find the path that is best for you and makes you better.
