Wedding Ceremony and reception

So... with less than 20 something days to go until my July 18 wedding, I found out from my pastor that we may have to move the ceremony outside. Also, we may not be able to have the reception inside our other church building. I’m at a crossroads and don’t know what to do. My FH and I are having a 2 tiered cake with a dessert buffet and bbq. But now everyone may end up having to be outside, after they get their food. So now I’m guessing we may only be able to have the DJ for the ceremony. We’ve done everything ourselves with no help and I don’t know what to do anymore to fix this situation. Ladies, I’m freaking out and need your advice. Sorry if this doesn’t make sense, I’m very stressed. How do we move everything outside? We really don’t have the budget to buy a tent and makeshift dance floor. That was all supposed to be in our other building. I’m hoping that this scenario doesn’t stick but if it does, ugh! Bouquet toss, garter toss, will this even happen? I’m freaking out, lol
