It's very hard to shake all that propaganda drummed into us in childhood. And being catholic meant confession and having to keep 'track' of my sins. I'm not atheist, I'm open-minded and have no idea what is true and what isn't. I enjoy Buddhist practices, and I also still feel a bit of a pagan with a connection to nature and mythology. I really have my own belief system that is impossible to label.
I have a feeling though if I was in plane which was about to crash I'd start saying Hail Marys.
I agree, it's hard to shake all the ingrained childhood indoctrination about religion. I do the same as you though AS, I have my own belief system, which is a kind of mix of many things what work for me, bits of different things I've tried.
