You’ve got to be kidding! My baby sister had just died, I had been sent away for 2 days and when I returned home there was no crib, no sign there had ever been a baby in the house. I was only 10 and no talk of heaven could make me stop crying for her. So, the dear sister looks for me, approaches me, and says she’s heard about my sister and that she thinks it is wonderful! Do you really think I cared about her reasons? I just thought she was the most cold-hearted person I had ever met. And YES, I WAS SHOCKED!!
You claim you were Catholic. This is standard Catholic teaching. You should have felt affirmed, not shocked.
Two things strike me:
1, you were poorly catechised.
2, you chose not to listen to the lessons that you were taught.
