Buy new car after car wreckage

Hi my name is Paul and I was in a car accident yesterday with my fiancé, Kim. We were driving home from a church event and the roads weren’t cleaned because it was New Years Day. The weather was terrible- I’m talking black ice and I don’t even know how many centimetres of snow. It was thick snow, there was no street lights, and you couldn’t even see where the edge of the road was. No one was on the road with us at the time, thankfully, but we ended up fishtailing and she couldn’t gain control of the car. We spun out, the car changed direction and we landed in the ditch which had water in it and by the grace of God ended up in between the two poles in the picture. We’re okay (aside from a bump on the head during the accident and a cut on my finger from pulling things out of the car after it was towed out of the ditch.)

We don’t have the expenses for both a car and wedding so any help would be appreciated.
