Kind of upset about it

So I’ve been ttc since October. It’s not going that well but that’s a story for another time. Well

A few days ago my cousin told me she was having her 3rd and was really pissed about it. She was praying that she’d miscarry and all. Well told she called me really happy about the fact that she miscarried and it pissed me off so bad that I just don’t even want to talk to her. Am I wrong for feeling this way?
