if you’ve got yourself a bump and a huge scar, what now?

Hello, my question is very simple and stupid, but I’m not a kfz-mechniker or spengler or anything. I missed when driving out of the garage,which was the wall still too close to the caprice, so I got a bump at the lower wheelbox at the back and the driver’s side,and a shramm from the back that looks like the car at jurassic park has laid out with a t-rex and won,because he “only” has a shramme,but a very deep one. therefore my question what do I do now? nd in front of all what is the procedure,I know would just be off to the workshop and ready,but I want to do this myself because I have a very bad certain,because I thought I could drive my baby.I know the question is strange but I can’t help it. thank you!
