Some insight about being rearended???

Yes you've read right. I was recently hit in the rearend by another car a few days ago while I was on vacation. The suck part is just that. The only thing I noticed wrong right after the accident was the rear bumper part was busted and scuffed and the tail pipe was bent a little. After looking closer at the car I noticed that on both sides of the rear corner panels have a bulge close to the bottom of the back glass. Instead of having the same margin crack on both sides of the trunk lid there is a bigger crack on the left side and a smaller crack on the right side. And underneath the car the rear part of the frame is bent downward and where the rear part of the bumper attaches to the part it's at least 3 inches away from where it suppose to go. Yeah I know they can pull some dents and stuff but I don't know how they can fix what looks like the rear side panels have moved outwards. I don't think they will total my car but I hate have something like this happen. Shows up on the cars history and just plain sucks. Anyone have the same thing happen and what did they do??? Thanks
