How do you live in a non Christian/non catholic family?

I am an ex-agnostic and ex-Protestant, but throughout my entire journey (I think I converted to Protestant Christianity a bit more than 2 years ago and to Catholic Christianity a few months ago) I have not talked my family into it. My parents are non religious theists and my older and younger sibling are atheists, as well as 99% of my friends being atheists as well. Hell I think me and my grandma are the only Christians in my extended family and she is Anglican anyway. Does anyone have advice for this situation, especially because my parents are sort of critical of religion/religious devotion? It is very difficult living in a non-Christian household, and I think it is the reason my home doesn’t really feel the same way a church does.
