Gutted for you mate.
Have a read of the book 'Who moved my cheese'. (http://www.amazon.co.uk/Who-Moved-My-Cheese-Amazing/dp/0091816971) which is a book dealing with change in your life and helping you move on, and getting you motivated again.
My mate used to swear by it and would read it every time something @*!# happened (broke up with a girl; lost his job etc).
I understood the concepts of it but it didnt really do much for me, but then, i've never really had to go through any hardships in my life.
It does sound like you're in a pretty rough place at the moment though mate... if that was me, i'd take advantage of it and get a new start. My favorite quote out of Fight Club is when Brad Pitt says 'It's only after we've lost everything that we're free to do anything.' I'm almost jealous of anybody who's in this position...! If i were at the point of effectively being free to start my life over again having lost close family members and my significant other, i'd pack it all up and be off round the world.
