Gender Reveal Ruined

I need to vent because I'm that mad.  My family is scattered around the country and decided to send out a card.  They said "that's stupid just give us a call".  I wanted to make it special I couldn't have a gender reveal party.  The front: "what will he or she bee" with a bee on it.  Inside is the old wives tales and a scratch card where you scratch the bee hive and it tells you what I'm having.  My parents demanded they get theirs first so I sent it out a day early.  I begged them multiple times to please not say anything.  They got it Wednesday and as of Thursday no one else got it.  On Thursday I realized I sent my brothers to the wrong address.  I panicked and called him.  I say to him and his wife "so do you want to know?" And they replied with "we already know, someone already got a card, and I spoke to mom and dad".  I called my parents and they laughed!  I called my brother and sister and my brother (who has no kids) tells me "you could have just called and your being too jazzy" then my sister (who only has a step child) says "just call.  People now a days have all these events and junk when it's not even worth it".  JUNK.  I tell her "it might be junk to you but it means a lot to me".  
I'm so upset.  I don't know why I even try anymore.
