Is it bad that I'm completely upset that my cousins husband keeps making plans and changing them when I'm trying to plan my baby shower so she can make it before she moves? I planned it on August 26th because he said that's the only day that will work, then all of a sudden he's planned a cruise trip for them around the same damn time. Then she tells me well maybe the 5th or the 12th of September but it's a maybe. Like, I don't even want a baby shower because I literally don't have friends to invite, I don't know if half my family can even make it. I'm so upset because all of my family made it to both of my sisters baby showers and I'm like shit out of luck here. Being the last one to finally have a kid has been so horrible because no one has been excited for me because the other 2 already took all the excitement they could give.. So I'm sitting here going through everything and my family is no where to be found. My oh so amazing support team is only around when they want too and it's literally killing me because I feel like I'm the only one excited about my child.. 💔😔
