One problem we have often had with my husband is that when I want to talk bout big issues, he is thinking about the small, day to day or minute-to-minute problems, and when he is ready to discuss life philosophies, I can only think about how to deal with the mucous in my throat right now.
Maybe if Harry could concentrate on controlling the few small things that he can control right now, the long-term big issues would be easier to deal with, or not deal with, at the moment.
I am really saying the same thing as Sue in the previous message: this may be the best he can do now. I know it is hard for you, pessimism is contagious.
All the best - Leena
