Dunno what year Civic you have but at the very least you will have bent a rear wishbone. Have a check under the back of the car tomorrow and have a look around. Something will be bent or kinked somewhere.

Start from the point of impact on the wheel and look closely at all the connecting bits to it.

Once you know what it is thats bent a trip to a breakers yard will be next on the cards.

I'd have a complete stab in the dark and say if your wheel is okay and not bent then your looking at around £60+ to fix.

Hope that helps you calm down a bit
