I'm also glad to hear that you are okay. I'm sending prayers and fast-healing thoughts your way.
I also agree that you should get a lawyer. If you are like most people, you probably don't want to take them to court to "stick it to them", but most companies do treat you a lot better if you have a lawyer after something like this. They hear the word "lawyer", and if they know that they are at fault, they settle on what is fair a lot faster, and with a lot less hassle.
Don't forget to buy a new helmet. Even if it looks fine, helmets are toast after a singificant impact like that.
