Sorry to read about this - not a good day for you!
If I were you I'd check for an appointment / repair with a local dent specialist. I had a firework land on the roof of my mkiv a few years back - it was a right nasty dent in a difficult place.
I rang a local (to me) dent specialist who managed to press it out without any issue at all.
If the paint isn't broken, then you may get away with this type of specialist repair - if the paint is cracked / missing, then insist on a proper bodyshop repair...
