So upset!!

My cousin has just had her baby girl. She knows we've been trying for a baby for 3 years and we're going through ivf. We've spoken about baby names and she knew I loved lily Amelia for a girl.. She's called her baby girl Amelia lily!!!!! I can't bloody believe it!! I'm devastated. I know we're not pregnant, but she has blatantly stolen our baby name if we do ever have a baby girl :-(
