Keith, I am so sorry. I buried my 15-year-old godson (and dear friend) a few years ago. Here's the deal, and you know it as well as I do. If you cave, you will have one more loss to face, which will diminish your presence when it is needed most.
God forgive me for saying it around here, but it's not so much about hanging on to "The Quit;" it's about hanging on to all we've got left. You gotta hang on for the people around you; you let go, you got nothing to offer them.
Go find a read Joe Cool if you need another harsh dose of truth therapy.
I stand with you, shoulder to shoulder.
