Having the opposite sex family wanted..

So the youngest girl in my family now is 18 and graduated high school. All the rest is little boys. Everyone wants me to have a girl in my family and I knew i was having a boy. When I found out for sure I knew everyone would be disappointed. That made me feel like crap cuz I'm excited and all I hear is how it better come out with a vagina. All out friends are excited, my middle sister is super excited. But my mom and older sister plus my nieces all are acting all weird cuz it's a boy. Has anyone els had to deal with a situation like this? Even if you haven't how would you deal with it.
