Holy crap, dude. That could have been much worse. Don't feel bad, it happens.
Sounds like you did everything you could and also didn't panic afterward.
I've never been upside down before, but I've been in a few wrecks. I usually hurt myself more in trying to make too hasty of an exit. I once tackled a lady that was going to run right into traffic after just a minor spinout accident. I guess it's human nature that we want to separate from the car asap, even more so in your case. Upside down and smelling gas, AAGGHH!
Did you have a few flashbacks? I always get the repeated replays in my head for the first night, I guess from the adreneline and the brain kind of de-fragging, but it goes away.
