Upset about my baby shower

Hi guys, I am just so upset about how the planning for my baby shower is going. It's the 28th of April and I'll be 36 weeks.... My family and I got together over a month ago to plan it and get everything ready but nothing has happened and I'm worried it will be a bust. Everything my husband or myself has suggested has been shot down. My oldest sister said she would send out invites and now she wants someone else to do it. As in no one has gotten any invitations. At all. She's also putting it all on my mom now that we're two weeks out. It's just getting on my nerves. We were supposed to go decor/shopping for the baby shower it self last weekend but everyone bailed and I had specifically requested that day off work to go. But anyways I'm just upset and needed to vent
