"but it isn't going to matter what I try...she is done"
That is why you fail. If you keep telling your self it's over then it will be over. If you say you aren't going to make the putt, you're not going to make the putt. Stop "trying" and just do. I'm not talking about pursuing your W more. Sometimes non-pursuit and building yourself up is doing something. You may not think so, but it is.
I totally understand about your kids. I feel the same way. What I do is to make the time that I have them, the best they can be.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
