Name taken

We've had a name picked out for months now and a friend that was very close in due dates just had her baby and used the name we picked out. She didn't know the name we had picked out and I didn't know hers but now I don't want to use the name and it's heartbreaking because I loved it and it's also a family name which is important to us. So frustrated right now :( and due in less than 4 weeks
