i don’t want to plan anymore

We found out last night (85 days out y’all) that our venue is no longer going to be able to host us. But don’t worry, the said they’d still do catering. We were getting it for free, so we didn’t have a contract, just a verbal agreement. I’m totally beating myself up over this.
We didn’t budget for this at all. In fact, we could barely afford it when it was free. Our invitations are already out, we have RSVPs coming in. We haven’t told anyone yet because we aren’t sure where to go from here. We don’t have a space at home large enough to host 50 people. Everything else in town starts at $1000, and I totally doubt anything would be available. I’m totally lost. Literally everything was planned out and I have to completely start over.
Please help, I just want to give up.
