Rain scheduled all wedding day

So I basically just need to rant a little bit but we specifically picked our venue for the beautiful outdoor ceremony spot right in front of a pond and we picked October 11th which it never really rains much in October over here. Well of course I've been checking the weather and it was fine saying it was going to be pretty hot and cloudy but yesterday of course it says rain Thursday, ALL DAY Friday(the wedding day), and Saturday as well as possibly dipping into the 40s at night. I'm honestly just praying for no rain in time for the ceremony bc I love the inside for the reception but I hate it for a ceremony I think I'll just cry all day if we have to do it inside not to mention my nephew(ring bearer) is currently sick and we are 6 days away and parking is literally on dirt so people will be walking through mud even if it just rains the night before and my MIL planned the whole wedding pretty much but hasn't talked about anything with me and keeps telling me one thing but then ends up another y'all I am just so stressed and FH is even more stressed so I'm trying not to talk about it but we don't even have our rings yet and our officiant still needs to go to the county clerk to "be official" and everything just keeps going wrong whether it's getting hurt in the dumbest way possible and ending up with an ugly scab on my left hand which will be photographed a few times I'm sure to having to worry about the rain.
