I guess I should also add that I only wetn through first communion and never finished catechism, so I’m not sure what my status is but I do consider myself Catholic
I’m sure a priest will help you with all your questions.
Having read your comments, I wonder when it comes to myself, as well. In my case, I married civilly to a non-Catholic — and still am. I joined his church. But, after fifteen years am considering going back to the Catholic church. The marriage and confession both confuse me. The latter because it’s been fifteen years — at least — since my last confession. In that time I could have broken every commandment but not remember.
If you were baptized Catholic then the Church will always consider you Catholic, even before First Communion. Find a different priest to help you, one with a good reputation if you know of any. I've been through this process before. If you have any questions I'd be happy to help. You can always call the diocesan offices for advice on where to start.
