Wow not sure how I missed this the first time around. Sorry I did, I really wish u all the best on this, man ohh man I wish I could help you carry the load. Only advice I can give is this, if you die on the inside the rest of you will soon follow. Sounds like u know it already though, they told my grandfather he had 6 months to live, he died in 3. He gave up, died inside the moment they told him and just passed on.
When you are really hurting, and really really down, then watch your friends and family when they are going about there days. Its amazing how just watching those you love when they dont realize it can help so much, makes you remeber what you are fighting for.
