Almost 27 days out

I wanted to elope but he said its very important for our families to be there and now our weddings 28 days away and not only with my family not be there but only 3 rsvp cards came back ! The deadline was 3 days ago !
However the reason my family cant come is understandable ! But it still hurts! My mom moved to texas because her boss offered to pay for her cancer treatment if she did, Texas has the best cancer center in America. She has custody of all my nieces and nephews and my 4 year old nephew for attacked by two dogs and is icu and has been awhile now and not getting out anytime soon. So she cant come which means her kids who were my bridal party cant either. Then my daughter and oldest niece who I consider a daughter had to fly up there to take care of the other kids because my mother cant leave the hospital so they wont be there either. My daughter could possibly come if I pay 320 for a plane ticket and she flies right back the next day but we dont have that . Because oddly enough my son just got out the hospital. He had to be given 4 liters of blood and we were there a bit. So spending money on food and stuff with none coming in hurt! I'm trying to be excited but honestly who can be excited with all this happening ? I'm trying to not bring my fh down also but I really dont want thos wedding without my family or atleast my daughter. Everything's paid and nothing is refundable so changing the date is not possible. And his family is flying here and already made plans to come. I'm just depressed about it so bad.
