I'm sorry it turned out the way it did. You fought like hell...you did everything you could have done...and then some. The feelings you're having are normal, and in time, they will go away. Millions of people have gone through the crap we're going through, and they went on to live happy and fulfilled lives. I believe that you will live a happy and fulfilled life too.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
