Babies not going to have a home

I’m currently 31 weeks pregnant with my second boy. My first is 1 and 8 months. Now when we got pregnant I was in such a good place. Up until 4 days ago. Our home got flooded by the tropical storm Imelda. I obviously can’t go in there with my son and with me being pregnant. We have 2 days to figure out where to stay because the place we’re currently staying at is being rented out in 3 days. I’m so upset because we lost our home while I was pregnant with my first due to Hurricane Harvey and we barely bought this new home 3 months ago. My fiancé is working his butt off trying to make money. While I’m trying to do all the paperwork I can. I can’t stop crying. I feel like I let my children down, again.
