Car accident and now?

Hi together, sorry for the maybe stupid question. I was just on the highway with my family when in a turn at more than 140 things a car rushed into the side. We were lucky, nobody was injured but my car is completely over to the right and on the left I am also in the limit. We have now changed the data and we could drive home. Now quite stupid: How is it going on? Do I claim to rent a car while my r is in the workshop? Is it best to go to the VW workshop or to my screwdriver? I don’t have any experience with this. Thank you!
