To many emotions.

I'm 21+3 weeks pregnant FTM. I've been in Michigan a year and my family resides in Louisiana. My mom was giving me a baby shower, told me not to stress about the things my baby will need because she has everyone pitching in. About a week ago she said she wanted to be here for the birth of the baby and that she is going to postpone my baby shower until after the baby is born. She wants me to pay for her travels. I expressed to her that I can't afford to get her here. I checked Amtrak, greyhound, and airlines. The cheapest would be $400 before taxes and doesn't include baggage, and that's only if we were to get the ticket now, in which I don't have the money. The closer it gets to Thanksgiving (my due date) the prices go up tremendously as you could imagine. I explained to her that I understand she wants to be here but it wouldn't be wise to spend all that money on a ticket when my baby has nothing. I have absolutely nothing for my baby yet. I'm struggling out here. It'll cost me at least $700 for a round trip ticket for her and she seems to not understand that. I just don't know how to feel and she's no longer throwing me a baby shower.
