Ok I realize this is confusing. Let me clarify.
I’ve had an on-and-off relationship with the Church my whole life. I was raised in the Church for 10 years, received baptism, catechism, first communion, ect - but this was mostly just all formalities to appease my grandparents. My parents were lapsed Catholics/nonbelievers and they didn’t encourage me to believe, so I didn’t at that point. That’s what I mean by a nonreligious background.
I came to the Church on my own when I was 14. I got a refresher catechism and received confirmation. I was a fully practicing Catholic for 3 years, but then scrupulosity and anxiety overwhelmed me and I left the Church out of despair - not because I stopped believing, but because my mental health was so poor that I felt I couldn’t take it anymore.
I don’t remember why I made this account in 2017 (which was a while after I left, by that point I would have been decidedly nonreligious in my lifestyle) but it was probably because I was contemplating coming back. Like I said, I didn’t leave out of a lack of belief. During the 4 years that I was away, every once in a while I would have a moment where I felt the urge to go back to mass, or ask a question about the faith, or something like that. Catholicism was always somewhere in the back of my mind, even though I was trying very very hard not to think about it.
Anyways so that’s my life story. I’m not technically a convert but I do somewhat think of myself that way because my religious upbringing was so bare-minimal.
I hope this clears up any confusion. The main point is that yes, I’m a returning Catholic and I’ve had all my sacraments and catechism, at one point or another. I guess the relevance of this is that I’m not walking into confession blind or unprepared.
