Man, that sound like a real hard hit. I'll keep you in my prayers. Thankfully, that helmet did what is was supposed to do.
If you don't mind might I suggest you consider a recumbent trike for future riding? There are no balance issues and no front fork to break in half. If your strap come alose it won't jam into the front tire because the front tires are to the side of you.
