Hey man, don't force it. It you're feeling out of it, take time off. Recovery's a slow process, especially after an accident like this.
I'm willing that you'll get through this shit as easily as possible. You're alive though and that's all you can ask for. XD
Good luck to you, good luck to everyone!
P.S: See, I was nice enough not to make a comment about the downsides of supposedly superior free health care that you Canadians have. cough painkillerscough
XD U.S for the win!
Seriously though, get well soon!
