baby shower flakes

Supposed to be having a shower with a bunch of friends today and literally everyone but 2 people have messaged or texted me telling me they couldn't make it... I'm literally heartbroken like how could you do that to a pregnant lady.. and 20 min before it's supposed to start how rude... I'm upset.. anyone else had this happen? My best friend went through a lot of effort to make this Happen and now I don't even want to go.. some friends..
