Is it hormones or do I have a right to be upset?

So I know that I am a little extra emotional lately, but I have been in tears for the last hour over my 3yo daughter's birthday party tomorrow. I wanted to make it a big deal for her since this is her last birthday as an only child.

I rented a pool for 3 hours because she loves to swim so much. Last year we rented the same pool for 2 hours and it just wasn't long enough, especially when there were so many people she was getting shuffled between. So I got it for 3 hours, which is like over $200. I ordered her a small cake. And we ordered like 4 dozen cupcakes. And of course we are ordering pizza as well. I invited 50 people.

As of now 17 for sure are coming. 17!!! I have lile 14 who said "maybe". Which I expected for one family because they have a pretty new baby. But with the others I feel like that is a polite way to get out of it.

What has me the most upset is that I planned it for tomorrow, Sunday, so that family would be able to make it, but literally over half of them aren't coming. I knew several have younger kids and it may be too late for them, but we literally had someone tell her yesterday that they would see her tomorrow for her party and then today say they had made other plans.

I know she won't even notice, but I can't help but feel like people just dgaf about her or her party. I wonder if it is my fault for making it on a Sunday evening (but she has other family with birthdays this weekend and I thought they would most likely do something on Saturday and wanted to plan her party when I felt like they could come.)

Am I being ridiculous? Would you guys be upset?
