Do we all have a cross to bear, or is it dependant on being raised Catholic?,

Maybe not a cross to bear but we all have baggage we carry, some of us wear shame like shackles on our feet

We are all human and we make mistakes. Some mistakes are worse than others and we have guilt. We have urges and that precipitates more mistakes. Oh well...

I have no cross to bear. If I’ve made mistakes, I’m over it.🙂

It’s a Catholic reference anyone can apply.

I just have a cross-eyed bear.

Yes.

I don't know what it is for Catholics, but the only time I hear that expression is in secular contexts.
