Is this trauma?

okay so I've been denying that I have trauma for a while(alot of people think I am traumatised though lol)but one thing that I think might be trauma is my view of christianity. So I was raised a little bit christian, not like intensly, I never went to church and religion didnt play much of a role in my life. Eventually I slowly just stopped believing in god and became an atheist for a while and everything was fine. But then I converted to paganism and this is where I just start to feel weird about christianity. One of the biggest things of this was when I was in Italy on a school trip and we were in this cathedral museum and I felt freaked out, the main thing I felt was judged, a sort of "you shouldn't be here" feeling. Then theres something I've noticed recently is that the concept of the christian god existing really freaks me out, like I panic at any implication of a christian god being real. In general christianity just makes me feel guilty and afraid.
