Damn, I'm sorry to hear that. But like everyone said, at least you're alive. Getting rear-ended while stopped in traffic is one of my biggest fears. Be glad you're not paralyzed, maimed or dead. And while it sucks that it's one less Buell, there are other Buells out there to be had. The bike can always be replaced. A leg, spine, brain, whatever, cannot.
Glad to see you're ok. FYI, in case you haven't already done so, make a folder with everything related to the accident (all the medical bills, visits, etc.). After I wrecked in 2003, my insurance tried to contest almost half of the bills from different specialists that I had to go see after I got out of the hospital. They tried to claim that since it was weeks after the accident, that some of the procedures weren't necessary and they didn't want to cover them. It took me 6 months (literally) of constantly writing letters, forwarding bills, forwarding my primary physician's notes, etc. just to get them to cover it all.
Good luck.
